When we rest in the finished works of Jesus, they empower us. This happens when we stop laboring in our works, and come to the realization that we need God to work for us. The good news contained in the Scriptures is the Gospel of His grace. This grace is available to everyone, and without it, there is no rest. This rest is found in the Sabbath, but the Sabbath is not a particular day—it is Christ Himself. We cannot earn His grace through our own merits. We need only to accept it by faith, and this trust brings us into His rest.
