Why Did I Write My New Book on Christian Ethics?
by Wayne Grudem
I wrote my new book Christian Ethics (Crossway, 2018) for Christians who want to understand what the Bible teaches about how to obey God faithfully in their daily lives. I hope the book will be useful not only for college and seminary students who take classes in Christian ethics, but also for all other Christians who seek, before God, to be “filled with the knowledge of his will in all spiritual wisdom and understanding,” with the result that they will live “in a manner worthy of the Lord, fully pleasing to him: bearing fruit in every good work and increasing in the knowledge of God” (Col. 1:9–10).
But the book also contains a challenge. I am concerned that teaching about ethics has been neglected in many evangelical churches today—partly because the issues seem complex, partly because pastors do not want to be accused of sounding “legalistic,” and partly because the surrounding non-Christian culture is hostile to Christian moral values, so anyone who teaches biblical ethics is likely to be criticized by unbelievers. Therefore, I hope this book will help to meet a need among Christians today for more biblical ethical understanding. And I hope the book will challenge Christians to live lives of personal holiness in the midst of a secular culture.
This book is similar in its method to my earlier book Systematic Theology, because both books seek to explain “what the whole Bible teaches” about various specific topics. However, Systematic Theology dealt with theological topics such as the Trinity, the person of Christ, the atonement, and salvation, while this book deals with ethical topics such as lying and telling the truth, war, abortion, euthanasia, racial discrimination, divorce and remarriage, homosexuality, stewardship of money, wise use of the environment, and many other topics.
I hope it will be useful for all Christians who seek to experience the great blessing of God that comes from walking daily in paths of obedience, knowing more of the joy of God’s presence, and experiencing his favor on our lives.Purchase this book

(1291 pages. This book is widely used as a theology textbook around the world. It has sold over 500,000 copies and has been translated into fifteen other languages, with at least four more foreign translations now in process — see Questions page for translation details.)
The Christian church has a long tradition of systematic theology, that is, studying theology and doctrine organized around fairly standard categories such as the Word of God, redemption, and Jesus Christ. This introduction to systematic theology has several distinctive features: – A strong emphasis on the scriptural basis for each doctrine and teaching – Clear writing, with technical terms kept to a minimum – A contemporary approach, treating subjects of special interest to the church today – A friendly tone, appealing to the emotions and the spirit as well as the intellect – Frequent application to life – Resources for worship with each chapter – Bibliographies with each chapter that cross-reference subjects to a wide range of other systematic theologies.Purchase this book
(This is a 619-page reference work that discusses over 60 political issues today, grouped into 18 broad categories in its 18 chapters. You can read the entire book, or each chapter can be read on its own for areas such as national defense, the environment, economics, marriage, the protection of life, or the courts.)Purchase this book
A variety of perspectives exist within the Christian community when it comes to political issues and political involvement. This comprehensive and readable book presents a political philosophy from the perspective that the Gospel pertains to all of life, so Christians should be involved in political issues. In brief, this is an analysis of conservative and liberal plans to do good for the nation, evaluated in light of the Bible and common sense.
In this ground-breaking book, recognized evangelical Bible professor Wayne Grudem rejects five mistaken views about Christian influence on politics: (1) ‘compel religion,’ (2) ‘exclude religion,’ (3) ‘all government is demonic,’ (4) ‘do evangelism, not politics,’ and (5) ‘do politics, not evangelism.’ He proposes a better alternative: (6) ‘significant Christian influence on government.’ Then he explains the Bible’s teachings about the purpose of civil government and the characteristics of good or bad government. Does the Bible support some form of democracy? Should judges and the courts hold the ultimate power in a nation? With respect to specific political issues, Grudem argues that most people’s political views depend on deep-seated assumptions about several basic moral and even theological questions, such as whether God exists, whether absolute moral standards can be known, whether there is good and evil in each person’s heart, whether people should be accountable for their good and bad choices, whether property should belong to individuals or to society, and whether the purpose of the earth’s resources is to bring benefit to mankind. After addressing these foundational questions, Grudem provides a thoughtful, carefully-reasoned analysis of over fifty specific issues dealing with the protection of life, marriage, the family and children, economic issues and taxation, the environment, national defense, relationships to other nations, freedom of speech and religion, quotas, and special interests. He makes frequent application to the current policies of the Democratic and Republican parties in the United States, but the principles discussed here are relevant for any nation.
This 2013 book was co-authored by me and by my good friend Barry Asmus, a professional economist. (Barry and I have also served together as elders at Scottsdale Bible Church.) For more information about Barry Asmus see http://www.barryasmus.com/In writing The Poverty of Nations, we found that our different academic backgrounds (Barry in economics, Wayne in Christian theology and biblical studies) led us to agree on the only way to solve world poverty.
Our solution is a complex one, ultimately involving seventy-eight factors. This is because we are convinced that the causes of continuing poverty are also complex. These seventy-eight factors fall in three categories that affect an entire nation: national laws, economic policies, and cultural values.
We think this book is unique because (a) it approaches world poverty from the combined perspective of Christian theology and economics, and (b) it approaches the question of poverty not at the level of the individual person or community (where much good work is already being done), but at the level of the whole nation.

(This is a 159-page condensation of my book Bible Doctrine, and it covers the 20 most central and basic doctrines of the Christian faith. It is suitable for use in a new members’ class in a church, or in a home study group.)
God doesn’t call every Christian to go off to seminary, but there are certain matters of doctrine—that is, the church’s teaching—that every Christian simply must know. Theology is important, because what we believe affects how we live. If you’re a relatively new believer in Jesus, or if you’re a more mature Christian looking for a quick brush-up on basics of the faith, Christian Beliefs is for you. This readable guide to twenty basic Christian beliefs is a condensation of Wayne Grudem’s award-winning book on systematic theology, prized by pastors and teachers everywhere. He and his son, Elliot, have boiled down the essentials of Christian theology for the average layperson and made them both clear and applicable to life. You will learn about the Bible, the characteristics of God, what it means that we are created in the image of God, what God has done for us in Christ, the purpose of the church, and much more. Each chapter includes questions for personal review or group discussion.
“These truly are twenty basic beliefs that every Christian should know. Wayne Grudem is a master teacher with the ability to explain profound truths in simple language. He is a man of deep conviction and theological passion—and those who read this book will be both educated and encouraged in the faith.” -R. Albert Mohler Jr., President, The Southern Baptist Theological Seminary, Louisville, Kentucky
“Based on Systematic Theology, this summary will certainly help beginners with Christ to get the hang of their faith.” -J. I. Packer, Regent College, Vancouver, British Columbia
“As Wayne Grudem’s Systematic Theology contracts into a compact book, I do not lose my enthusiasm for the truth he loves and the clarity of his words.” -John Piper, Bethlehem Baptist Church, Minneapolis, MinnesotaPurchase this book
(96 pages) Can business activity in itself be morally good and pleasing to God? Sometimes business can seem so shady–manipulating the “bottom line,” deceiving the consumer, or gaining promotions because of whom you know.
But Wayne Grudem introduces a novel concept: business itself glorifies God when it is conducted in a way that imitates God’s character and creation. He shows that all aspects of business,including ownership, profit, money, competition, and borrowing and lending, glorify God because they are reflective of God’s nature.Though Grudem isn’t naïve about the easy ways these activities can be perverted and used as a means to sin, he knows that Christians can be about the business of business.
This biblically-based book is a thoughtful guide to imitating God during interactions with customers, coworkers, employees, and other businesses. See how your business, and your life in business,can be dedicated to God’s glory.
(This is a 528-page condensation of my book Systematic Theology.)
How do we know the Bible is God’s Word? What is sin, and where did it come from? How is Jesus fully God and fully man? What are spiritual gifts? When and how will Christ return? If you’ve asked questions like these, then ‘systematic theology’ is no abstract term. It’s an approach to finding answers every Christian needs to know. Bible Doctrine takes a highly commended upper-level textbook on systematic theology and makes it accessible to the average reader. Abridged from Wayne Grudem’s award-winning Systematic Theology, Bible Doctrine covers the same essentials of the faith, giving you a firm grasp on seven key topics: The Doctrine of the Word of God, The Doctrine of God, The Doctrine of Man, The Doctrine of Christ, The Doctrine of the Application of Redemption, The Doctrine of the Church, and The Doctrine of the Future. Like Systematic Theology, this book is marked by its clarity, its strong scriptural emphasis, its thoroughness in scope and detail, and its treatment of such timely topics as spiritual warfare and the gifts of the Spirit. But you don’t need to have had several years of Bible school to reap the full benefits of Bible Doctrine. It’s easy to understand…and it’s packed with solid, biblical answers to your most important questions.Purchase this book

My first recommendation is Jay Richards’ excellent book, Money, Greed, and God: Why Capitalism is the Solution and Not the Problem (New York: HarperOne, 2009). In addition, see my annotated list of other helpful (and not so helpful) books on economics here:
- 1. David Landes, The Wealth and Poverty of Nations: Why Some Are So Rich and Some So Poor. (1999). Landes is professor emeritus of economics at Harvard and also taught at George Washington University. This is a masterful survey of the history of economic development in the entire world, by region, over the last 500 years.
- 2. Lawrence E. Harrison, The Central Liberal Truth: How Politics Can Change a Culture and Save It from Itself (New York: Oxford Univ. Press, 2006). Argues in extensive detail that culture makes all the difference in economic development, and explains how cultures can change. Pp. 88-89 give a table showing vastly greater per capita GDP in Protestant-background countries than for any other religious group: the rest are, in order: (2) Jewish, (3) Catholic, (4) Orthodox, (5) Confucian, (6) Buddhist, (7) Islam, (8) Hindu.
- 3. Hernando De Soto, The Mystery of Capital: Why Capitalism Triumphs in the West and Fails Everywhere Else. An excellent, insightful book about the need for people to have the right to own property and relatively easy access to obtain a publicly documented title to that property, in order for an economy to grow and people to overcome poverty.
- 4. William Easterly, The Elusive Quest for Growth (he has also written The White Man’s Burden more recently but I have not read it yet). Why aid to Africa has never really solved the problems of poverty in Africa.
- 5. P. T. Bauer, Equality, the Third World, and Economic Delusion. Bauer died in 2002. He was emeritus professor of economics at London School of Economics and a specialist in development economics. He tells in detail why all the British aid to African countries over decades did more harm than good: It distorted local economies and entrenched corrupt governments in power, and had many other negative consequences.
- 6. Robert Guest, The Shackled Continent (anecdotal; written by Africa editor for The Economist). He describes in vivid detail the barriers to economic development in Africa.
- 7. Brian Griffiths, The Creation of Wealth (taught at London School of Economics and was adviser to Margaret Thatcher; now in House of Lords). Gives principles for a Christian perspective on how economies grow.
- 8. Bjorn Lomborg, The Skeptical Environmentalist . Lomborg shows that we are not running out of any natural resource, and we won’t run out in the future. But the world is short on knowledge of true facts about the state of natural resources. (Lomborg is a professor of statistics from Denmark.)
- 9. Several writings of Julian Simon, esp. The Resourceful Earth, and The State of Humanity, and The Ultimate Resource II. (Simon was a professor of business and economics in Maryland.)
- 10. Dambisa Moyo, Dead Aid: Why Aid is Not Working and How There is a Better Way for Africa (2009). Moyo is from Zambia, has a MA from Harvard and a Ph.D. in economics from Oxford. She was a consultant for the World Bank and then worked at Goldman Sachs. Her argument foreign aid has done more harm than good for Africa and has trapped nations in poverty: It entrenches corrupt African governments in power, provides “fungible” money that funds profligate lifestyles, creates internal conflicts for control of vast wealth, removes government accountability to the citizens of a country, creates a mentality of dependence, prevents beneficial investment, and has never brought any African country out of poverty. But she wrongly believes that if foreign aid is stopped, good governance “will naturally emerge” (p. 143.).
B. Here are some books on economic systems in general, and the great flaws of socialism and government control:
- * 11. Jay Richards, Money, Greed, and God: Why Capitalism Is the Solution and Not The Problem (HarperOne, 2009). This is now my #1 recommendation for people who want to understand economic systems from a Christian point of view.
- 12. Arthur Brooks, The Battle: How the Fight Between Free Enterprise and Big Government Will Shape America’s Future. (Basic Books, 2010). Brooks argues that what gives people genuine satisfaction in the economic realm is not to be given money but to achieve “earned success” – the opportunity to have a responsibility (even if small) and to do well at it.
- 13. Friedrich Hayek, The Road to Serfdom. Hayek was Austrian and fled from Hitler. He became an economics professor at London School of Economics. He watched with dismay as socialism grew in England. He explains how government control expands inch by inch until it takes over all of life. This is an all-time classic that was written in 1944, with a 50th anniversary edition released in 2004.
- 14. Henry Hazlitt, Economics in One Lesson. Hazlitt was a long time editor at the Wall Street Journal. This book was first published in 1946 and has become a classic. It is a wonderful book that explains how every action in the economy has more than one consequence, and when we realize this we can understand better how an economy works.
C. Here are two books that I found unpersuasive (or wrong) in terms of explaining why nations become wealthy:
- 14. Jared Diamond, Guns, Germs, and Steel (I found this unconvincing because it was completely materialistic and deterministic, from an entirely evolutionary perspective, allowing no role for human choice and decisions and initiative. He thinks physical geography determines everything!)
- 15. Jeffrey Sachs, The End of Poverty (I found this unconvincing for the most part, because I heard him saying that we have given X amount of money in the past but that has not solved the problem so the solution is that we need to give X + 1 or even 2X the amount and that will solve the problem). Sachs is an economics professor but he also has another job advising the United Nations how to give such money away.

This is a great disappointment and a direct challenge to the moral standards taught in the Bible, which I believe to be the Word of God.
I cannot think of another instance where an American president has declared himself to be in such direct contradiction to the moral teachings of the Bible (see Romans 1:26-27).
The institution of marriage is a way for society to decide what kind of relationship it will promote by calling it “marriage” and giving it numerous legal and financial benefits. For centuries, societies have decided that they will promote marriage between one man and one woman because that is by far the best relationship for raising the children of the next generation, and also the best protection for women against abandonment and the best way to encourage men in socially beneficial pursuits. Society has a strong interest, therefore, in promoting marriage between one man and one woman. We should treat homosexuals with love and kindness, but government should not promote such relationships by calling them “marriage.”
But in this announcement, President Obama has given a clear signal of his agenda if he wins reelection. His administration will continue to actively promote (through laws and policies) a sexual relationship that is contrary to the Bible, contrary to most people’s moral instincts (according to how they consistently vote, even if they aren’t willing to tell that to pollsters), contrary to the way God designed our human bodies to function, and, sadly, harmful to the parties involved, harmful to the next generation of children, and harmful to the nature of marriage itself as understood through all societies in previous human history. (See the discussion in my Politics — According to the Bible, chapter 7.)
In addition, supporters of same-sex “marriage” have already shown that they will promote social and economic ostracism and sometimes even criminal penalties (for “hate speech”) against anyone who expresses public opposition to their view. Such conduct significantly threatens freedom of speech, freedom of conscience, and freedom of religion in our nation.
What does this mean for President Obama’s future? The Bible also says that God is sovereign over the affairs of nations. “The Most High rules the kingdom of men and gives it to whom he will” (Daniel 4:25 ESV). Also, “it is God who executes judgment, putting down one and lifting up another” (Psalm 75:7 ESV).
I will watch carefully for the next several months to see whether this sovereign God will bless or frustrate the plans of a national leader who takes the stand President Obama has taken. I do not expect that God will bring blessing to a president who has taken such a stand.
I have discussed this issue at some length in a recent podcast in Minnesota. KTIS radio podcast – Minnesota
I see that you endorsed John Piper’s book, This Momentary Marriage. Does this mean that you agree with Piper’s view that remarriage is never justified after a divorce?
No, I do not agree with my friend John Piper on that matter. But I thought I could endorse the book anyway because there is so much excellent material in it.
My own view of divorce and remarriage is expressed well in the article on marriage, divorce, and remarriage in the ESV Study Bible (pp. 2545 – 2547), and also in the ESV Study Bible notes on Matthew 5:31-32; Matthew 19:3-9; Mark 10:2-12; Luke 16:18; and 1 Corinthians 7:15.
In brief, my own view is the mainstream evangelical Protestant view since the Reformation, the position which is also represented in the Westminster Confession of Faith (1646). In brief, that position is that marriage is a life-long commitment, but that divorce is morally justified, and is not sin in God’s sight, if the other spouse (a) has committed adultery, or (b) has abandoned the marriage and all attempts at reconciliation have failed.
In such cases where divorce is morally justified, it is allowed by God but not necessary, and, if possible, reconciliation and attempting to preserve the marriage should be the first choice. But when a divorce has occurred for one of these reasons, then the marriage no longer exists, and the spouse who obtained a divorce because of such a reason is viewed as a single person in God’s sight and is free to marry someone else. (See the ESV Study Bible notes referenced above for further explanation).
The short answer is that I moved because of my wife Margaret’s health. That is explained in this article:
But now after several years I can see that God had additional purposes for this move, because the time here has been wonderfully blessed by God through fellowship with faculty colleagues, through relationships with students, through Scottsdale Bible Church, and through many other circumstances that have made it possible for me to be very productive in my writing projects (see books section).
