Commentaries:
As the Creator of the Sabbath (John 1:1-3, 14; Colossians 1:16-18), Jesus is "Lord of the Sabbath." As a man, He showed us the intent of this commandment in numerous accounts recorded in the four gospels. Jesus gave His church an example of how the whole Christian way of life is to be lived (I John 2:6). We are to do as Christ did (I Peter 2:21-22).
