"Praise the LORD, for the LORD is good; sing praise to his name, for that is pleasant." (Psalm 135:3)
Psalm 135 is a great hymn of praise that draws together themes from earlier psalms and weaves them into a sustained doxology. It opens with a triple Hallelujah, calling all servants of the LORD to praise, and gives the reason: the LORD is good, his name is pleasant, he has chosen Jacob for himself. The basis of worship is not human achievement but divine election: he chose us before we were worthy of being chosen. What follows is a recital of God's acts in history and in nature: he sends lightning and brings out wind from his storehouses, he struck down the firstborn of Egypt, defeated Sihon and Og, gave their land to Israel as an inheritance.
The idol polemic that follows mirrors Psalm 115: the idols of the nations are silver and gold, made by human hands, they have mouths but cannot speak, eyes but cannot see. Those who make them become like them. But the conclusion for Israel is the opposite: those who trust in the LORD will praise him, and in praising a living God, they become alive. The Catechism teaches that the liturgical praise of God is not a human performance for divine entertainment but a participation in the divine life that transforms the worshipper (CCC 2097). Praise is formative. The God you praise shapes you into his likeness.
Brothers and sisters, praise the LORD, for the LORD is good. Not because you feel like it this morning. Not because circumstances have been kind. Because he is good, as a fact about his nature, which does not change with your circumstances. Sing praise to his name, for that is pleasant: pleasant for him to receive and pleasant for you to give. Try it and discover that this is true.
Praise the LORD! His name endures forever and his renown through all generations. He will vindicate his people and have compassion on his servants. Blessed be the LORD from Zion. Through Christ our Lord. Amen.
