John 21: 20-23 Peter turned and saw that the disciple whom Jesus loved was following them. (This was the one who had leaned back against Jesus at the supper and had said, “Lord, who is going to betray you?”). When Peter saw him, he asked, “Lord, what about him?” Jesus answered, “If I want him to remain alive until I return, what is that to you? You must follow me.” Because of this, the rumor spread among the believers that this disciple would not die. But Jesus did not say that he would not die; he only said, “If I want him to remain alive until I return, what is that to you?”
Some scholars realized that on the night he was betrayed, Thomas showed another expression of unbelief when: “… Lord, we do not know where you are going; how to know the way? ” A few days earlier, when Jesus decides to go to the dead Lazarus, Thomas, perhaps mocking the decision, says to the group: “… we too are going to die with him.” The Hebrew word Thomas means twin as does the Greek word Didymus.
The question about Thomas‘s absence from the first appearance in the Upper Room is: What was Thomas doing in a attonished city by the last events? His absence is recorded by John (John 20:24), but not justified. I suppose Thomas that was having trouble believing. It may be necessary to get out of a place, to be alone, and to seek answers to the doubts that arise. How many times do we need to be alone to remember the words that brought us to the Way. Thomas’s life is an example of a man who wanted to believe. He had difficulties but he recognized that. And he did not depart from those who believed. Jesus made five appearances on Sunday, the day he was resurrected. I think He wanted to mark Sunday as the day of Christ’s resurrection. That is why Voltaire said: “To destroy Christianity, we must first destroy Sunday.”
After the entire week, He reappeared on Sunday. Thomas perceives the misundertanding who paid for not believing in the testimony of his fellow brothers. But it was necessary for him. He had to believe. He wanted to believe. From that test, he would have no more doubts. He would live for it. C.S.Lewis remarked us that 99% of the things we believe are accepted by authority. That is, you believe what your teachers and mentors say. You pay attention what your parents advise. You trust the institutions and the authorities. We need to believe in ideas, give credit to people. We need to trust.
What Thomas said about Christ is that the world is saying to the church, “If we do not see the sign of the nails in our hands, we will not believe.” If we have the marks of Christ, we need to show the world. This is the answer to the lack of faith.
