above learntoswim has claimed that working on the sabath was a law made by man and not God and jesus was mocking the pharases by not following it. However this is not true the law of not working on the sabath was from God himself.
See exodus 31
12 And the L ord spoke to Moses, saying, 13 "Speak also to the children of Israel, saying: 'Surely My Sabbaths you shall keep, for it is a sign between Me and you throughout your generations, that you may know that I am the L ord who sanctifies you. 14 You shall keep the Sabbath, therefore, for it is holy to you. Everyone who profanes it shall surely be put to death; for whoever does any work on it, that person shall be cut off from among his people. 15 Work shall be done for six days, but the seventh is the Sabbath of rest, holy to the L ord . Whoever does any work on the Sabbath day, he shall surely be put to death.
This brings me back to my original question if the Jesus regarded life above the law following him would be to accept blood in order to save a life.
