The truth of Christianity rests primarily on the resurrection. If Jesus rose from the dead who saw Him? It is clear from the Bible Jesus appeared to the following after He died:
The other women at the tomb
Peter in Jerusalem
The two travelers on the road
Ten disciples behind closed doors
All the disciples, with Thomas (excluding Judas Iscariot)
Seven disciples while fishing
Eleven disciples on the mountain
A crowd of 500
Jesus’ brother James
Those who watched Jesus ascend into heaven
Can we really believe these witnesses? Those who claimed to see the risen Christ were changed. Most of them turned the world upside down and many died for what they believed.
1 Corinthians 15:6
"After that He appeared to more than five hundred brethren at one time, most of whom remain until now, but some have fallen asleep."
