Grace

Let us take care, on the other hand, because we are not under law but under grace, not to forget the thought of man's rest and also of God's rest. As we pointed out before, rest is the special mark of God's own people. When we come to Christ, He gives us rest, and when we take His yoke upon us, we find rest to our souls. To the servant of the Lord who is wearied in the service of his Master (not wearied of His service), we read of another rest: "Come ye yourselves apart into a desert place, and rest a while," and there alone in the presence of His Master, far from the rush and toil, He finds rest and refreshment, and comes forth freshly girded for His work.
As to those saints who have left us and are "with Christ", they rest from their labors; they are at home with their Lord in Paradise. (See 2 Cor. 5:8 and Luke 23:43.)
