"And the Lord make you to increase and abound in love ... to the end he may stablish your hearts unblameable in holiness" (1 Thessalonians 3:12-13)
True holiness is a sense of awareness of the other world, a mysterious quality and difference that has come to rest upon some. Now, if a man should have that sense and not be morally right, then I would say that he is experiencing a counterfeit of the devil.
Whenever satan has reason to fear a truth very gravely, he produces a counterfeit. He will try to put that truth in such a bad light that the very persons who are most eager to obey it are frightened away from it. satan is very sly and very experienced, and pawns his parody off as the real thing and soon frightens away the serious-minded saints.
I regret to say that some who have called themselves by a kind of copyrighted name of holiness have allowed the doctrine to harden into a formula which has become a hindrance to repentance, for this doctrine has been invoked to cover up frivolity and covetousness, pride and worldliness.
The Spirit cannot fill whom He cannot separate, and whom He cannot fill, He cannot make holy, and whom He cannot make holy, He cannot make happy!
