Proverbs 14:14

Note, 1. The misery of sinners will be an eternal surfeit upon their sins: The backslider in heart, who for fear of suffering, or in hope of profit or pleasure, forsakes God and his duty, shall be filled with his own ways; God will give him enough of them. They would not leave their brutish lusts and passions, and therefore they shall stick by them, to their everlasting terror and torment. He that is filthy shall be filthy still. "Son, remember," shall fill them with their own ways, and set their sins in order before them. Backsliding begins in the heart; it is the evil heart of unbelief that departs from God; and of all sinners backsliders will have most terror when they reflect on their own ways, Luk 11:26. 2. The happiness of the saints will be an eternal satisfaction in their graces, as tokens of and qualifications for God's peculiar favour: A good man shall be abundantly satisfied from himself, from what God has wrought in him. He has rejoicing in himself alone, Gal 6:3. As sinners never think they have sin enough till it brings them to hell, so saints never think they have grace enough till it brings them to heaven.
