Deuteronomy 26:11

Thou shalt rejoice — Thou shalt hereby enabled to take comfort in all thy employments, when thou hast sanctified them by giving God his portion. It is the will of God, that we should be chearful not only in our attendance upon his holy ordinances, but in our enjoyment of the gifts of his providence. Whatever good thing God gives us, we should make the most comfortable use of it we can, still tracing the streams to the fountain of all consolation.
