ESUS is Lord! He possesses all power and owns all authority. He is the King of all kings and the Lord of all lords. He is the Boss. The fact is, if an individual can get this issue settled in his or her mind and be happy with it, salvation will suddenly be seen on the bottom shelf. "He who comes to God must believe that He exists and that He rewards those who diligently seek Him," that is that He is the Boss and that He is good. Everything else in soteriology is attached (one way or another) to those 2 facts.
Now, during His earthly ministry, Jesus had an agenda. He wanted to trim away all the artificial piety and substitute rituals that were eclipsing His gracious Father. One of the main issues (that the religious Jews had to get over) was the Jews' overemphasis on the rules surrounding their "holy Sabbath" day. They had made so many rules about the Sabbath that they had eliminated everything that was holy about it. Jesus shocked them with His disregard for their man-made traditions. It is rather obvious that Jesus went out of His way to violate their rules in order to reveal their hypocrisy.
Whether it was defending His disciples for "harvesting" on Saturday or healing publicly Saturday, Jesus made it abundantly clear that He rejected any and all reverence-of-cultural-rules above God's law. He despised how distracted these religious people were with things that didn't matter (while simultaneously they totally ignored things that did matter). It is a common error of superstitious humans.
