Joel Beeke
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.

Come to me, all who labor and are heavy laden, and I will give you rest. Take my yoke upon you, and learn from me, for I am gentle and lowly in heart, and you will find rest for your souls.
Matthew 11:28-29
