Prominent atheist scholars are quoted in each chapter to introduce the challenges, and then scholarly arguments and evidence are presented to defend the Christian worldview. The language is simple enough, but the material is solid enough to use in a real debate. I would say that introductory books like this one are more than enough to equip you for everyone who will challenge you.
Why are these 18 topics important? Because these are the questions that atheists ask. These are the questions that cause Christians to leave the faith. These are the questions that your children will face in high school and college, which might cause them to leave the faith.
Let’s start with chapter one. One of the most prominent arguments by atheists is that faith is irrational. This chapter allows you to define faith using the Bible’s definition of faith, which relies on logic and evidence.
Atheists also say that Christianity is at war with science. In chapter 2, they discuss the history of science and how Christianity provided the framework that allowed scientific method to take root and flourish.
Atheists like to claim that miracles are impossible. Chapter 3 defends the view that God, if he exists, is capable of interacting with his created world.
Atheists love to put forward Darwinism as means to deny that God is the designer of life. Chapter 4 explains the concept of intelligent design, and why intelligent design is a better explanation for the history of life.
Atheists love to talk about how the universe has always existed, and there’s no need for a Creator. Chapter 5 contains a philosophical argument that is supported by mainstream science to argue that the universe had a beginning, just like the Bible says.
Atheists love to argue that life can emerge from non-life, and the process is simple. Chapter 6 is written by a biochemist, and it takes a look at the real complexity of the simplest living cell.
Atheists like to argue that the universe itself is just an accident, and there is no need for a Designer. Chapter 7 introduces the scientific evidence for fine-tuning and habitability.
Atheists like to say that there is no soul and no afterlife. Chapter 8 gives some arguments for the existence of the soul.
Atheists like to argue that Christians invent God because God makes them feel good. But chapter 9 explains that having an all-powerful God who can hold humans accountable is the last thing any human would want to invent.
Atheists like to talk about how religion, with it’s habit of teaching to believe in things that can’t be tested, causes religious people to do a lot of harm. Chapter 10 takes a look at the real record of Christianity as a force for good in the world.
Atheists like to talk about slavery in the Bible. Chapter 11 talks about what the Bible really says, and provides some rational responses to the accusation.
Atheists like to talk about eternal punishment in Hell isn’t a just punishment for just getting a few questions wrong on a theology exam. Chapter 12 provides an explanation and defense of the concept of Hell.
Atheists love to talk about how God commanded the Israelites to attack their enemies in the Bible. Chapter 13 explains who their enemies really were, and what was really happening in those wars.
Atheists feel that unrestricted sexual activity is very healthy and normal, and that the Biblical prohibitions outside of male-female marriage are repressive and unhealthy. Chapter 14 explains why God has these rules in place, and supports his rules with evidence.
Atheists love to assert that they don’t need God, because they can behave morally on their own. Chapter 15 explains how to answer this claim by talking about how well atheism grounds objective moral values, objective moral duties, free will and moral accountability: the minimum requirements for objective morality.
Atheists think that the mere existence of natural disasters and human immorality are incompatible with the God of the Bible. Chapter 16 explains why this argument doesn’t work, and why even the concept of evil requires God to exist.
I have an atheist friend in my office who can’t defeat my scientific arguments for the origin of the universe, the fine-tuning and the origin of life. But still, he says to me, even if God exists, why would that matter to my life? Chapter 17 explains what difference Christianity makes in a person’s life.
Atheists think that the life of Jesus has no relevance to their life, and that he has nothing to offer them anyway. Chapter 18 explains the uniqueness of Jesus and explains why his resurrection is relevant to our lives today.
It’s important to understand that this book is not on the level of A. W. Tozer, G.K. Chesterton, Francis Chan, John Piper, etc. Those authors write for a Christian audience and therefore they do not equip you to answer realistic challenges from non-Christians. But the apologetics book we looked at actually equips you to answer challenges from non-Christians using logical arguments and evidence from mainstream history and science. You can use the material in that book in discussions outside the confines of your home and your church.
