Thomas Brooks

"It is not the hearing of truth, nor the knowing of truth, nor the commending of truth, nor the talking of truth, but the indwelling of truth in your souls, that will keep your judgments chaste and sound, in the midst of all those glittering errors that betray many souls into his hands, that can easily 'transform himself into an angel of light' (2 Cor 11:14), that he may draw others to lie in chains of darkness with him for ever."
