Jesus often gave a postscript after he healed someone — go wash in the pool, pick up your mat, go show yourself to the priest, see that you don’t tell anyone. Jesus healed a man who had been an invalid for 38 years and my human nature is wondering, exactly how much sinning can a man who has been an invalid for 38 years do? Because of his limitations he probably wasn’t involved with prostitutes, nor was he a thief, or a murderer. I suppose that while laying around the pool at Bethesda he could have been trash-talking, telling dirty jokes, or reading pornography. The man did not know who healed him, but Jesus had yet one more postscript to add to the healing, “Later Jesus found him at the temple and said to him, “See, you are well again. Stop sinning or something worse may happen to you” (John 5:14 NIV).
