Rejoice not only in salvation, but in the God of salvation, the God who rejoices to save, who sings with joy over those He saves: The Lord your God is in your midst, a mighty one who will save. He will rejoice over you with gladness. He will quiet you by His love. He will exult over you with loud singing (Zephaniah 3.17). The chief end of man is to glorify God first, and to enjoy Him in no other way than as a saving God.
Rejoice in His salvation, not as an end in itself, but as fuel for worship, gratitude, service, evangelism, and patient enduring. The lepers rejoiced greatly, but only one returned to give thanks to the healer, Jesus. A sort of selfishness can accompany the topics of joy, gladness, comfort, peace, and so forth. Are we careful to reflect back the grace and good we receive? To multiply it, share it, and show it? Think of the shame involved with the beggars outside the walls of Samaria who found the ready-made banquet (2 Kings 7).
Rejoice more in this divine salvation than in anything else, or than everything else (Luke 10.20). The stuff of life is, at once, put in its place by rejoicing in Christ first and showing how easy it is to eclipse the light of His countenance when we turn to lesser things instead of Him. Our Savior is jealous over us, and will allow no rival. – William J. Gorrell (born in 1961), based on a devotional article by William Jay (1769-1853)
