People are destroyed by the devil every day because they do not have the breastplate of righteousness to defend their hearts against his murdering shot. If God had made you famous and rich in the world, but not holy, He would have given you nothing more than fuel for hell. How then can we forget to thank God for His precious breastplate of righteousness?
When an enemy approaches a city without walls or arms for defense, the wealthier the city the worse the destruction. And each time Satan comes to a man who has much of the world but nothing of God in his soul to defend him, he makes a miserable wreck of the person. He takes whatever he pleases and does whatever he wants with such souls. The devil's plundering possession is so thorough that the captive would not think of postponing or denying a lust. Although he knows what this fulfillment will cost him in hell, he goes ahead and damns his soul rather than stand against the burning demands of temptation.
Herod threw down half his kingdom at the feet of a malicious wench; and when she decided this was not enough, he sacrificed everything he had. But if the blood of John the Baptist cost Herod his throne in this life, surely it was nothing compared to the wages of divine providence paid immediately when he met death.
But let the saints humbly shout "Hallelujah!" When God made you a holy man or woman He gave you gates and bars to your city. Now through His grace you are able to defend yourself with the continual comforts which heaven sends to withstand Satan's power. Once you were a timid slave to him but now he is under your feet. The day you became holy God firmly planted your foot on the serpent's head. Your lusts-- mighty strongholds which gave him easy control-- have been taken out of his hand. Satan has been dislodged and can never again set himself up as king of your soul.”
