C S Lewis

There is no doctrine which I would more willingly remove from Christianity than this, if it lay in my power. But we cannot do so, for two reasons: first, because it enjoys the full support of Christ’s own teaching; and second, because it makes a good deal of sense. If the gospel is extended to us for our acceptance, it must be possible also to reject and refuse it. The alternative would be for God to compel an affirmative response.
