In Observance of the Sabbath, we need to be able to be led by the Holy Spirit, because under Grace and Truth, there's more of an approach that does away with the ceremonial approach of the Law and tends to guide us in can I say a more humanitarian approach. In which we relieve burdens, and help the afflicted as with Jesus healing the man with the withered hand, which was a chronic condition but was in Jesus' power to do good on the Sabbath.
