The question can be asked, “Why do we as the church not keep the Sabbath commandment when we keep the other nine?” Some contend that the reason is simply because Jesus affirmed all the other commandments but He never affirmed the Sabbath. I, however, believe there is a much better explanation. In order to answer this question I will begin by explaining what the Sabbath was in the Old Testament and Jewish culture.

Exodus 20:8-11 and Hosea 6:6
