Right after Jesus feeds 4,000 with just a few loaves and fishes he is asked to give a sign. What could they have been looking for? Jesus has already feed thousands, healed dozens and cast out demons. When you do not believe, no amount of evidence will ever be enough. Even the Disciples still do not grasp the full truth. It is not about things here on this plane; Jesus has that covered. It is having eyes to see and ears to hear the things of God which brings truth.
To see, sometimes means to leave the village. How many conversations has Jesus had with people outside of the village, away from the city. Now he takes a blind man out to the countryside to help him to see. And this is right after he chastised the Disciples for not seeing.
Peter must have learned something because now he can see Jesus for who he is, the Christ. But Peter’s sight is still not clear. He needs Jesus to touch his eyes one more time to see things as they really are.
Jesus teaches the true way to the Kingdom of God. It is through compassion and love for others. But it must end at the cross. We must all take up the cross, forsake the world of men, the religious traditions, and the expectations of others. We must live the life of the cross, which is sacrifice for love and compassion.
