The great thought which lies here is that we best requite God by thankfully taking what He gives.
I. Note how deep that thought goes into the heart of God. We requite God by taking rather than by giving, not merely because He needs nothing, and we have nothing which is not His. The motive of His giving to us is the deepest reason why our best recompense to Him is our thankful reception of His mercies. The principle of our text reposes at last on "God is love, and wishes our hearts," and not merely on "God has all, and does not need our gifts."
II. Look at the elements which make up this requital of God in which He delights. (1) Let us be sure that we recognise the real contents of our cup. It is a cup of salvation, however hard it is sometimes to believe it. (2) Be sure that you take what God gives. There can be no greater slight and dishonour to a giver than to have his gifts neglected. (3) One more element has still to be named: the thankful recognition of Him in all our feasting. "Call on the name of the Lord." Only he who enjoys life in God enjoys it worthily. Only he who enjoys life in God enjoys it at all.
