Pious public exultation is becoming to God's people. Even Calvin declared that there was no better exercise in which the people of God could be employed than praise. It is a great privilege to praise the Lord. It refreshes the heart, revives the spirit, and excites others to do the same. We have countless reasons for praising the Lord.
Praise is commanded.
Confess the Lord with the harp. Sing praises with the psaltery and ten stringed instruments. If you don't feel like praising, then PLAY until you do. Stir your heart to praise the Lord. Praise is personal.
