Dwight L. Moody
The power of a simple gospel tract, placed in the hands of a willing servant of God, can never be underestimated. It can lead a soul to Christ and transform a life of eternity.

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.
