166 LORD, I have hoped for thy salvation, and done thy commandments.
Here is the whole duty of man; for we are taught, 1. To keep our eye upon God's favour as our end: "Lord, I have hoped for thy salvation, not only temporal but eternal salvation. I have hoped for that as my happiness and laid up my treasure in it; I have hoped for it as thine, as a happiness of thy preparing, thy promising, and which consists in being with thee. Hope of this has raised me above the world, and borne me up under all my burdens in it." 2. To keep our eye upon God's word as our rule: I have done thy commandments, that is, I have made conscience of conforming myself to thy will in every thing. Observe here how God has joined these two together, and let no man put them asunder. We cannot, upon good grounds, hope for God's salvation, unless we set ourselves to do his commandments, Revelation 22:14. But those that sincerely endeavour to do his commandments ought to keep up a good hope of the salvation; and that hope will both engage and enlarge the heart in doing the commandments. The more lively the hope is the more lively the obedience will be.
