John Wesley on 1 Chronicles 29:14

To offer - That thou shouldest give us both riches to make such an offering, and a willing heart to offer them, both which are the gifts and the fruits of thy good grace and mercy to us. Of thine - We return only what we have received, and therefore only pay a debt to thee. The more we do for God, the more we are indebted to him; for the honour of being employed in his service, and for grace enabling us in any measure to serve him.
