Catechesis: Free Will

In spiritual and divine things the unregenerate person’s intellect, heart, and will are utterly unable, by his natural powers, to understand, believe, accept, think, will, begin, effect, do, work, or concur in working anything. They are entirely dead to what is good. They are corrupt. So in mankind’s nature since the fall, before regeneration, there is not the least spark of spiritual power remaining or present. No person can prepare himself for God’s grace or accept the grace God offers.—FC SD II:7
