In John 6:66-71, many of Jesus' followers are leaving Him. He had quite a crowd following Him thanks to the feeding of the 5000 and healing crowds of people, but when they realized He wasn't going to keep feeding Him most of them left. Jesus asks His disciples if they are going to leave too, and this is their answer:
"Lord, to whom shall we go? You have the words of eternal life. We believe and know that You are the Holy One of God."
They had gotten beyond the physical world and its desires. For them it was ok to not understand what Jesus was doing. They could accept what God had planned even if it did not fit their own plans.
I am sure that their thoughts were not as complete as what I have written, but the foundation was there. They stayed with Him to the end.
I pray that we would be as faithful.
