We are accustomed not only to say “grace,” but “free grace.” It has been remarked that this is a tautology. So it is, but it is a blessed one, for it makes the meaning doubly clear and leaves no room for mistake. Since it is evidently objectionable to those who dislike the doctrine intended, it is manifestly forcible, and therefore we will keep to it. We feel no compunction in ringing such a silver bell twice over — grace, free grace.
CH Spurgeon
Sermon No. 1524, p122
