The mind is darkened, we know little of God. Ever since Adam did eat of the tree of knowledge, and his eyes were opened, we lost our eye-sight. Original sin has defiled the heart. It is a lesser hell. The heart is, Officina diabolic 'the devil's shop or workhouse,' where all mischief is framed.
Contumacy is the seat of rebellion.
These, as the strings of a viol, are out of tune. They are the lesser wheels, which are strongly carried by the will, the master wheel. Our affections are set on wrong objects. Our love is set on sin, our joy on the creature. So we have impure lustings instead of holy longings.
