He did not say “for the Jews,” but for man, and there is no justification for confining the meaning to less than all of mankind.
If we thus confine the word, we will soon come into great difficulty. For example, we read that Christ is “the true light, which lights every man that comes into the world.” John 1:9.
Q: Did Christ bring light only to such men as are Jews?
Furthermore, the Sabbath was given so that men might have the blessing of rest and the worship of their Creator.
Q: Why should God desire that only a small fraction of His created beings—for the Jews have ever been but a very small part of the world's population—should partake of the happiness of rest and worship?"
