Give thanks to the LORD, for He is good; His loving devotion endures forever.
PSALM 118 At the time when this psalm was penned, whenever that was, David having attained to the possession of royal power, and aware that he reigned for the common safety of the Church, calls upon all the children of Abraham to ponder attentively this grace. He also recounts his dangers, the magnitude and variety of which would have slain him a hundred times, had not God wonderfully succored him.
Commenting on Psalm 118:1-29
O give thanks unto the Lord. The grateful hero feels that he cannot himself alone sufficiently express his thankfulness, and therefore he calls in the aid of others. Grateful hearts are greedy of men's tongues, and would monopolize them all for God's glory. The whole nation was concerned in David's triumphant accession, and therefore it was right that they should unite in his adoring song of praise.
It appears here, as often as elsewhere, that David had his heart full of the goodness of God. He loved to think of it, loved to speak of it, and was very solicitous that God might have the praise of it and others the comfort of it. The more our hearts are impressed with a sense of God's goodness the more they will be enlarged in all manner of obedience.
