When a man is saved by divine grace, he is not wholly cleansed from the corruption of his heart. When we believe in Jesus Christ all our sins are pardoned; yet the power of sin, albeit that it is weakened and kept under by the dominion of the new-born nature which God doth infuse into our souls, doth not cease, but still tarrieth in us, and will do so to our dying day.
