Then he appeared to more than five hundred brothers at one time, most of whom are still alive, though some have fallen asleep. 1 Corinthians 15:6
He presented himself alive to them after his suffering by many proofs, appearing to them during forty days and speaking about the kingdom of God. Acts 1:3
So, according to the Bible there was this period of forty days when a man raised from the dead appeared to more than 500 people. Paul tells us the numbers while Luke wrote in the Acts of the time period. That's a serious crowd and one active dead fellow! Of course, raised to life again, the resurrection, means that He was not dead, but alive. And just to take the tale a bit further out there, it was an angel who asked, "Why do you seek the living among the dead?" (Luke 24:5). And it is this story from the Bible that causes many to refuse to believe. So... the part they have the most difficulty with is not so much about faith, but about believing eye witness testimony? It does seem to all come in a package: if one believes in Jesus first, then one believes all the testimonies too. If another one believes all the witnesses first, then it follows that the one will also next believe in the One they bear witness of, Jesus the Christ.
And we pray for those who choose to believe neither of them!
