Jesus had put himself in a difficult situation. Not only was he vulnerable, and in fact Judas betrayed him, but no one could follow Him: “Where I am going you cannot follow me NOW,” Jesus tells Peter. After asking so many people to follow Him during his ministry, NOW not even Peter could follow him, much to his disbelief.
What is so special about NOW? Why did Jesus call people to follow Him before and Peter could follow Him after, but not NOW? Now is the hour. The hour, in the gospel of John, is a technical term to explain the moment when the hour of darkness and hour of glory meet.
Basically our Christian lives can be understood as following Jesus, which means to go where He is going. He went to the Father, which is why Christian life is simply about how to go to the Father. However, this section of His journey is for Him alone. Only Jesus, because He is man, He can be vulnerable to be reached by man’s sins; but, the same time, because He is God, He can attract and exhaust the sin of the world.
Only after the Son had finished this section of the journey, can we, as God’s children, follow him.
