It is not every man who can be a Christian, even in a very moderate sense, whatever education you give him. It is a matter of constitution and temperament, after all. He may have to be born again many times. I have known many a man who pretended to be a Christian, in whom it was ridiculous, for he had no genius for it. It is not every man who can be a free man, even.
