Entering into God's Rest

Hebrews Chapter 4 teaches that the heart of Sabbath-keeping is entering into God's rest, both in the Old Testament and in the New. In the New Testament the day is changed to the first day of the week to mark our Lord Jesus' entering into his rest as God did following the creation. Sabbath-keeping is not imitating God's rest, but entering into it--into God's own contemplation and thought--into the deepest level of communion with God and salvation itself from our native disposition to be absorbed in earthly things. In the worship of the New Covenant we are called away from the world into Christ's own rest and delight in his greater work than creatioin.
