Charles H. Spurgeon on Psalms 116:7

Return, unto thy rest, O my soul. He calls the rest still his own, and feels full liberty to return to it. What a mercy it is that even if our soul has left its rest for a while we can tell it —"it is thy rest still." The Psalmist had evidently been somewhat disturbed in mind, his troubles had ruffled his spirit but now with a sense of answered prayer upon him he quiets his soul. He had rested before, for he knew the blessed repose of faith, and therefore he returns to the God who had been the refuge of his soul in former days. Even as a bird flies to its nest, so does his soul fly to his God. Whenever a child of God even for a moment loses his peace of mind, he should be concerned to find it again, not by seeking it in the world or in his own experience, but in the Lord alone. When the believer prays, and the Lord inclines his ear, the road to the old rest is before him, let him not be slow to follow it. For the LORD hath dealt bountifully with thee. Thou hast served a good God, and built upon a sure foundation; go not about to find any other rest, but come back to him who in former days hath condescended to enrich thee by his love. What a text is this! and what an exposition of it is furnished by the biography of every believing man and woman! The Lord hath dealt bountifully with us, for he hath given us his Son, and in him he hath given us all things: he hath sent us his Spirit, and by him he conveys to us all spiritual blessings. God dealeth with us like a God; he lays his fulness open to us, and of that fulness have all we received, and grace for grace. We have sat at no niggard's table, we have been clothed by no penurious hand, we have been equipped by no grudging provider; let us come back to him who has treated us with such exceeding kindness.
