“Peter turned and saw that the disciple whom Jesus loved was following them… 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.'” (John 21:20-22)
There is a popular argument for not believing that Jesus is the only way to heaven. How could Jesus be the only way to heaven when not everyone on the planet has even heard about Jesus? Would a just and loving God condemn people to hell for the crime of growing up where they never heard about Jesus?
There is more than one approach to this question, but one of the most important is that introduced by the example of Jesus and Peter in the dialogue above. Peter is wondering how John was going to die, and Jesus says, “What is that to you? You must follow me.”
What about the guy who grows up a Buddhist and never hears about Jesus? The answer is the same: “What is that to you? You must follow me.”
One has to already know a good deal about Jesus to even be asking this question, and to use it as an excuse not to believe is ludicrous. That’s saying you are not going to be accountable to what you know about Jesus, or could find out if you tried, because there is a guy somewhere in the world who in your estimation can’t find out anything.
When Jesus said: “You follow me,” He was saying: “You follow what you know of me — what has been revealed to you. You are not responsible for what has been revealed to someone else; that is between my Father and that person.”
This also applies to our experience in life. When you want to compare your life to someone else’s — someone else has had it better or worse than you — guess what Jesus says. “What is that to you? You must follow me.”
