In vain people busy themselves with finding any good of man's own in his will. For any mixture of the power of freewill that men strive to mingle with God's grace is nothing but a corruption of grace. It is just as if one were to dilute wine with muddy, bitter water.
John CalvinIf people mean that man has in himself the power to work in partnership with God's grace they are most wretchedly deluding themselves.
John CalvinWere the judgments of mankind correct, custom would be regulated by the good. But it is often far otherwise in point of fact; for, whatever the many are seen to do, forthwith obtains the force of custom. But human affairs have scarcely ever been so happily constituted as that the better course pleased the greater number. Hence the private vices of the multitude have generally resulted in public error, or rather that common consent in vice which these worthy men would have to be law.
