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,
Luke xi. 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. vi. 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.
