There is perhaps no other fact more important to the Christian faith than the resurrection of Christ. Indeed, Paul writes, “And if Christ be not risen, then is our preaching vain, and your faith is also vain” (1 Cor. 15:14).
This is a topic that has been given a thorough treatment by theologians and apologists. Ashby Camp has written a concise point by point treatise on the matter, The Historical Case for the Resurrection of Christ. If you have not read other similar works, this paper is concise and thorough. I recommend it.
