As the Way, Jesus enables us to go to God.
Both Peter and Thomas indicated that they did not know where Jesus was going, but that is certainly not because Jesus hadn’t revealed that to them, not only had he just told them that He was going to prepare a place for them, but Jesus had previously spoken frequently of the fact that he had come from the presence of His Heavenly Father and that He was going to return to His Father.
As the Truth, Jesus enables us to fully know God.
We often say, seeing is believing, but sometimes the most real things in the world are the things you can’t see. In effect Jesus is saying, it is not seeing that leads to believing, but rather believing that leads to seeing. If His followers want to see what God is really like then they merely need to believe in Him because He reveals Himself to those who believe in Him.
As the Life, Jesus enables us to grow with God.
We see repeatedly in the gospels’ accounts that the disciples really didn’t want Jesus to go to the cross and die.
