"The doctrine of irresistible grace is easily understood. Once we understand the condition of man in sin, that he is dead, enslaved to a corrupt nature, incapable of doing what is pleasing to God, we can fully understand the simple assertion that God must raise the dead sinner to life. That is all, really, the phrase means: it has nothing to do with sinners rebelling against God and 'resisting' Him in that way. It has nothing to do with the fact that Christians often resist God's grace in their lives when they sin against Him. No, irresistible grace means one thing: God raises dead sinners to life."
-James R. White from The Potter's Freedom
