The Theology of Thomas if you know anything about Jesus then you know about Thomas the doubter. Thomas needed proof to believe that Jesus died and rose again. He had to see the proof for himself once he saw the proof only then did he believe. Jesus has blessed those who believe without proof of scarves. Thomas was a disciplewho believed when Jesus was with them in the natural but once he was crucified, died, Thomas had a problem with believing Jesus had rosed from the grave.
