On Keeping the Heart (Prov. 4:23)

There is only so much of worth in what we do, as there is of heart in it.

The greatest difficulty in conversion, is to win the heart to God; and the greatest difficulty after conversion, is to keep the heart with God.

The heart of man is his worst part before it is regenerated, and the best afterward; it is the seat of principles, and the fountain of actions.
