But Jesus here, very clearly, is speaking very gently to his person. This is a very personal and individual statement that Jesus is making to one specific person. Jesus understands, apparently, that in this case this man's problem, his physical problem, is a manifestation of his crushing sense of guilt. Now, having a huge burden of guilt is like driving with an over-loaded trailer. Your life is like the car that's carrying a huge trailer.
Nothing seems to work quite right.
The acceleration is just not there. You're always aware of it. It's always dragging you down and holding you back. Human beings carry a lot of guilt. It's part of the way we are.
