My final reading assignment in my New Testament class was the end of the four gospels where it talks about the resurrection. I found it very surprising, again, that Thomas didn't believe that Jesus had come back. There are a couple of reasons for this.
First, if you believed that Jesus was the son of God when you knew him and witnessed all of his miracles and if he told you that he was coming back, how could you not believe it when it actually happened?
Second, if all of your must trusted and closest friends told you that they had actually seen Jesus on the earth again, how in the world would you not believe them? It would only take one of my friends to convince me. Thomas had all of the other disciples plus Mary and who knows how many others and he still wouldn't believe it. My thought was, "How did this guy get picked to be a disciple?"
The comforting thought in all of this is that he did get picked to be a disciple and there was probably a very good reason for it. He was normal! He was human! He was imperfect, just like all of us. He represented all of those who are still on their faith journey and who might need a little more convincing. If Thomas, with his limited faith, could be chosen to stand as a witness of God and Christ then there is hope for all of us:)
