Charles H. Spurgeon on Psalms 68:33

And that a mighty voice; or a voice of strength; a strong and powerful voice, such as the gospel is, when accompanied with the power and Spirit of God. It is a soul shaking and awakening voice; it is a heart melting and a heart breaking one; it is a quickening and an enlightening voice; it quickens dead sinners, gives life unto them, and the entrance of it gives light to dark minds; it is a soul charming and alluring one; it draws to Christ, engages the affections to him, and fills with unspeakable delight and pleasure. John Gill.
