The difficulty with pragmatic arguments for a religion is that truths do not always work, and beliefs that work are by no means always true.

In 56 A.D. [the apostle] Paul wrote that over 500 people had seen the risen Jesus and that most of them were still alive (1 Corinthians 15:6ff.). It passes the bounds of credibility that the early Christians could have manufactured such a tale and then preached it among those who might easily have refuted it simply by producing the body of Jesus.
