Making Sense of God is focused on promoting reasons why we need to believe in the existence of God.34 In this book, Keller shows how much of what we believe to be true—e.g., meaning, satisfaction, freedom, self, identity, hope, morality, and justice—are nonsensical unless the God of the Bible is also true. They cannot exist without a transcendent God who made us, loves us, and saves us. I believe we can use this approach in the art of positive apologetics.
