Apologetics is not the right way to ask forgiveness. Apologetics is the art and science of defending what you believe. One of the most accessible apologists we have is Mark Mittelberg and his very helpful book Questions Christians Hope No One Will Ask.
I have taken a passage from the Bible as my guideline for defending the Christian faith. The Apostle Peter wrote:
But in your hearts set apart Christ as Lord. Always be prepared to give an answer to everyone who asks you to give the reason for the hope that you have. But do this with gentleness and respect, keeping a clear conscience, so that those who speak maliciously against your good behavior in Christ may be ashamed of their slander. (1 Peter 3:15-16)
Focus on Christ … Be prepared to answer … Answer gently and respectfully. In this book, Mark Mittelberg arms Christians with information to help them do just that. He doesn’t shy away from the tough questions like the apparent disharmony between Science and the Bible, or God’s existence, or Christ’s divinity. All of these he addresses using Scripture, philosophy, science, and logic. Mittelberg frequently quotes both Christian and atheist apologists to help make his point. And he does so very winsomely.
Each chapter is designed as sort of a lecture and lab. Mittelberg teaches, and then he walks through some possible conversations and objections an atheist or non-Christian may have about Christian’s beliefs. s
It’s a helpful and enjoyable read.
