We are all sinners by nature, therefore we are held under the yoke of sin. But if the whole man is subject to the dominion of sin, surely the will, which is its principal seat, must be bound with the closest of chains. - John Calvin

“We are all sinners by nature, therefore we are held under the yoke of sin. But if the whole man is subject to the dominion of sin, surely the will, which is its principal seat, must be bound with the closest of chains. And indeed if divine grace were preceded by any will of ours, Paul could not have said that, ‘it is God that worketh in us to will and to do'” (Phil. 2:13)

–John Calvin
