Psalm 149:3-4
Let them praise his name with dancing, making melody to him with tambourine and lyre! For the Lord takes pleasure in his people; he adorns the humble with salvation.

The Puritans, then, were not afraid to use the law of God as an instrument of evangelism. When God is about to play the chord of grace in the soul, they taught, he usually starts with the bass note of the law.
