When Peter was told by Christ Jesus how he would die, he asked about how John would die. In a nutshell, Jesus responded to him, “that’s none of your business.”
“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?” This is the disciple who testifies to these things and who wrote them down. We know that his testimony is true.” (John 21:20-24)
It was almost Peter’s attempt at weighing how fair it is for him to die such a way compared to the others, specifically the one Jesus seemed to have been most attentive to.
Some of us today are hoping that if we were to enter eternity this very minute, we would get an opportunity to ask Jesus if we could see at least one of our enemies in hell. What would be terrifying then is to have that very person standing next to us, smiling with tears of joy for seeing us at last. God destroys our enemies by causing them to repent.
In the end, Christ simply said, “You must follow me.”
What is essential is that we follow Christ, nobody else, but Christ Jesus. We are to follow him for everything he is to us and everything he has promised us.
