What the Bible says about Enforcement of Law as Tyrannical
(From Forerunner Commentary)
The Jews do not ask him, "Who healed you?" but "Who told you to carry your bed?" (verses 11-12). They are not in the least interested in the wonderful miracle that had been performed to make this man whole and vigorous. They are focused on what they perceive to be an offense against themselves—against their laws, power, desires, and pride. Essentially, if it meant breaking their rules, they would rather let people suffer than have them healed on the Sabbath.
The Jewish leaders' laws had become their god. They had long since forgotten that "the Sabbath was made for man, and not man for the Sabbath" (Mark 2:27). They were unable to recognize that the Sabbath is given to provide rest from an exhausting world and to rejuvenate people's relationship with God. Also, as this miracle typifies, healing brings rest from spiritual pain and suffering. However, these Jewish critics prefer the role of religious dictators and policemen oppressing the people. If enforcement of law only tyrannizes people and increases unnecessary suffering, it becomes harmful and worthless.
