Origen

“ And therefore it must not be said that it is because God is incapable of persuading men that they are not persuaded, but because they will not accept the faithful words of God. And if one were to apply this expression to men who are the “artificers of persuasion,” [4] he would not be wrong; for it is possible for a man who has thoroughly learned the principles of rhetoric, and who employs them properly, to do his utmost to persuade, and yet appear to fail, because he cannot overcome the will of him who ought to yield to his persuasive arts. ”
