Let us take care that our own personal religion is real, genuine, and true. The saddest symptom about many so-called Christians is the utter absence of anything like conflict and fight in their Christianity. They eat, they drink, they dress, they work, they amuse themselves, they get money, they spend money, they go through a scanty round of formal religious services once or twice every week. But the great spiritual warfare—its watchings and strugglings, its agonies and anxieties, its battles and contests—of all this they appear to know nothing at all. Let us take care that this case is not our own. The worst state of soul is “when the strong man armed keepeth the house, and his goods are at peace”—when he leads men and women “captive at his will,” and they make no resistance. The worst chains are those which are neither felt nor seen by the prisoner. (Luke xi. 21; 2 Tim. ii. 26.)
We may take comfort about our souls if we know anything of an inward fight and conflict. It is the invariable companion of genuine Christian holiness. It is not everything, I am well aware, but it is something. Do we find in our heart of hearts a spiritual struggle? Do we feel anything of the flesh lusting against the spirit and the spirit against the flesh, so that we cannot do the things we would? (Gal. v. 17.) Are we conscious of two principles within us, contending for the mastery? Do we feel anything of war in our inward man? Well, let us thank God for it! It is a good sign. It is strongly probable evidence of the great work of sanctification. All true saints are soldiers. Anything is better than apathy, stagnation, deadness, and indifference. We are in a better state than many. The most part of so-called Christians have no feeling at all. We are evidently no friends of Satan. Like the kings of this world, he wars not against his own subjects. The very fact that he assaults us should fill our minds with hope. I say again, let us take comfort. The child of God has two great marks about him, and of these two we have one. HE MAY BE KNOWN BY HIS INWARD WARFARE, AS WELL AS BY HIS INWARD PEACE. [all caps are Ryle's.]~ J.C.
