Love is the greatest thing that God can give us; for Himself is love: and it is the greatest thing we can give to God; for it will also give ourselves, and carry with it all that is ours. The apostle calls it the band of perfection; it is the old, and it is the new, and it is the great commandment, and it is all the commandments; for it is the fulfilling of the Law.
From David learn to give thanks for everything. Every furrow in the book of Psalms is sown with the seeds of thanksgiving.
