When people think of the Sabbath they most often think of things you can't do... but the "rest" that comes from the Lord is entirely different. Jesus absolutely "fulfilled the law" by His life and practice and He DID do what the Father wanted Him to do ... often on the Sabbath when the Pharisees were most critical of those actions of Jesus. Why? What was the difference Jesus was wanting to give the people? What was it that Jesus completely completed before the Cross?
