Here is the classic defense of the Resurrection of Jesus by Josh McDowell, one of the most popular Christian apologists in the world. His books, including "Evidence That Demands a Verdict" have provided satisfying answers to millions of sincere seekers of truth regarding the claims of Christianity:
For centuries many of the world's distinguished philosophers have assaulted Christianity as being irrational, superstitious and absurd. Many have chosen simply to ignore the central issue of the resurrection. Others have tried to explain it away through various theories. But the historical evidence just can't be discounted.
A student at the University of Uruguay said to me. "Professor McDowell, why can't you refute Christianity?"
"For a very simple reason," I answered. "I am not able to explain away an event in history--the resurrection of Jesus Christ."
