Charles H. Spurgeon on Psalms 32:7

Songs of deliverance. In that he will not be content only with thanks, but also will have them conjoined with songs, he letteth us see how high all the strings of his heart are bent that he cannot contain himself for the mercies of God to his church, and for his manifold deliverances for the same. Many sing praises to God with an half open mouth; and, albeit, they can sing aloud any filthy ballad in their house, they make the mean, I warrant you, in the church, that scarce can they hear the sound of their own voice. I think they be ashamed to proclaim and show forth God's praises, or they fear to deafen God by their loud singing; but David bent all his forces within and without to praise his God. Archibald Symson.
