Regeneration presuppose Total Depravity

"The idea of regeneration presupposes that men are sinners. This does not mean simply - ah, yes, even the statement that men are sinners requires explanation, for Protestants and Catholics, Calvinists and Arminians, differ as to what sin is - so this does not mean simply that men, even all men, occasionally do something wrong. It means that they were born in sin and in sin did their mothers conceive them. It means that all human beings are totally depraved, i.e., sin affects their total personality, and that therefore they cannot save themselves, or even help to save themselves from that condition." -Gordon H. Clark, The Holy Spirit, Pg. 31-32
