Sabbath of the 4th Commandment

Moreover also I gave them my sabbaths, to be a sign between me and them, that they might know that I am the Lord that sanctify them. Ezekiel 20:12.

As the Sabbath was the sign that distinguished Israel when they came out of Egypt to enter the earthly Canaan, so it is the sign that now distinguishes God’s people as they come out from the world to enter the heavenly rest.

The observance of the Sabbath is the means ordained by God of preserving a knowledge of Himself and of distinguishing between His loyal subjects and the transgressors of His law.

It [the Sabbath] belongs to Christ.... Since He made all things, He made the Sabbath. By Him it was set apart as a memorial of the work of creation. It points to Him as both the Creator and the Sanctifier. It declares that He who created all things in heaven and in earth, and by whom all things hold together, is the head of the church, and that by His power we are reconciled to God. For, speaking of Israel, He said, “I gave them my sabbaths, to be a sign between me and them, that they might know that I am the Lord that sanctify them”—make them holy. Then the Sabbath is a sign of Christ’s power to make us holy. And it is given to all whom Christ makes holy. As a sign of His sanctifying power, the Sabbath is given to all who through Christ become a part of the Israel of God....
