The Bible has no record of anyone asking Jesus to heal him on a Sabbath. They knew better. Jesus took the initiative in all his Sabbath healings, and always chose situations where the person had been infirmed for a long time. He could have postponed these healings until after sundown or to a following day; but his Sabbath healings were intentional. He wanted to show that Sabbath and wholeness are interconnected. He wanted to free the day for healing and joy.
