That footsteps in the sand thing is dead on accurate.
And isn't it amazing that Jesus always seems to have the same size feet as the person he's carrying.
If the person is in a heavy wheelchair, do the wheelchair tracks turn into footsteps that are really irregular and deep in the sand?
That "footsteps in the sand" imagery is so annoying. No matter what the trouble, Jesus will see you through it. If the person does not have faith, it is their own fault. Right. Many people pray and pray for heavenly help, and don't get it. Many, many people have given up hope in terrible situations and committed suicide or gone insane, or gotten lost in drugs and alcohol.
I guess in those cases, the footsteps would be sliding around and then there would be a big hole where Jesus dropped the person.
