Trick question: Saturday is a day dedicated to God, it is recommended not to make any deeds of our own in this day, but to make what is Divine. What means own deed? Eh, for example work. And what is God’s deed, is it a deed that pleases God? We need to ask straightforwardly to God Himself, in order to answer this question, or to really know who He is. It is of course simpler not to work and to forbid in general all that is similar to work. Pharisaic interpretation of the law was effectively alike, that's why they {Pharisee} always accused Jesus of breaking the law of the Sabbath with His healings. But the Lord Jesus endeavors to heed people to the living God, He means through His question to people: what is the nature of your God? Is He good or bad? What His will consists of - to save the lives or to let die? Do you know your God? These questions are also been asked to us today, Pharisees answered by a silence; and we, what are we going to answer?
