Psalms 104:31

The psalmist concludes this meditation with speaking, I. Praise to God, which is chiefly intended in the psalm. 1. He is to be praised, (1.) As a great God, and a God of matchless perfection: The glory of the Lord shall endure for ever, Psa 104:31. It shall endure to the end of time in his works of creation and providence; it shall endure to eternity in the felicity and adorations of saints and angels. Man's glory is fading; God's glory is everlasting. Creatures change, but with the Creator there is no variableness. (2.) As a gracious God: The Lord shall rejoice in his works. He continues that complacency in the products of his own wisdom and goodness which he had when he saw every thing that he had made, and behold it was very good, and rested the seventh day. We often do that which, upon the review, we cannot rejoice in, but are displeased at, and wish undone again, blaming our own management. But God always rejoices in his works, because they are all done in wisdom. We regret our bounty and beneficence, but God never does; he rejoices in the works of his grace: his gifts and callings are without repentance. (3.) As a God of almighty power (Psa 104:32): He looks on the earth, and it trembles, as unable to bear his frowns - trembles, as Sinai did, at the presence of the Lord. He touches the hills, and they smoke.
