There is now a popular argument against Christianity whereby a skeptic states that "I don't think the truth of Christianity follows if Jesus rose from the dead, it just shows a man rose from the dead".
There are a few issues with this argument, but the one glaringly obvious one is that as a rule, people do not rise from the dead. Popular shows like The Walking Dead tell stories of dead bodies becoming reanimated, but they are still in a sense dead. The Highlander tells the story of a man named Connor MacLeod who is an immortal - that is, when he is killed, he rises again (unless you cut off his head).
Both of these are not what the Bible means when they refer to resurrection. The resurrection was more than Christ coming back from dead. Christ had raised Lazarus during his ministry. But Lazarus died again. The dead who rose at the end of Matthew's Gospel died again. But Jesus is alive and does not die again. In fact, His body was changed to a glorified body - showing His wounds as evidence that He was the Christ and to glorify His sacrifice for sins. The proof text of this is in 1 Corinthians 15
"So is it with the resurrection of the dead. What is sown is perishable; what is raised is imperishable. 43 It is sown in dishonor; it is raised in glory. It is sown in weakness; it is raised in power. 44 It is sown a natural body; it is raised a spiritual body. If there is a natural body, there is also a spiritual body. 45 Thus it is written, “The first man Adam became a living being”;the last Adam became a life-giving spirit. 46 But it is not the spiritual that is first but the natural, and then the spiritual. 47 The first man was from the earth, a man of dust; the second man is from heaven. 48 As was the man of dust, so also are those who are of the dust, and as is the man of heaven, so also are those who are of heaven. 49 Just as we have borne the image of the man of dust, we shall also bear the image of the man of heaven."
But, there is also the fact that Jesus predicted His own death and resurrection and told this to the disciples. If Jesus really performed all of these miracles, proclaimed Himself to be the Son of God, predicted His death and resurrection from the dead and then in fact was crucified, died, and was buried and rose three days later as He predicted, there are no other reasonable explanations that explain this other than He in fact was the Son of God. It then naturally follows that what He said was true. This includes His teachings from the OT. It also follows that His disciples proclaimed His teachings and were willing to die for what they heard and saw.
This objection fails because it does not take into account what it means to be resurrected, Jesus life and ministry and the rarity of resurrection itself. The objection also does not give credible explanations that are backed by evidence. It's simply an alternate explanation. But, alternate explanations are not refutations as Greg Koukl of Stand To Reason so aptly states.
The Resurrection of Christ would be the most powerful piece of evidence for the truth of Christianity.
