I was in 2 Corinthians 10 this morning and read: 3 For though we walk in the flesh, we are not waging war according to the flesh. 4 For the weapons of our warfare are not of the flesh but have divine power to destroy strongholds. 5 We destroy arguments and every lofty opinion raised against the knowledge of God, and take every thought captive to obey Christ, (ESV)

Then I read from Spurgeon’s Morning by Morning these words that give insight into how this works:

There is no motive for holiness so great as that which streams from the veins of Jesus. And “precious,” unspeakably precious, is this blood, because it has an overcoming power. It is written, “They overcame through the blood of the Lamb.” How could they do otherwise? He who fights with the precious blood of Jesus, fights with a weapon which cannot know defeat. The blood of Jesus! sin dies at its presence, death ceases to be death: heaven’s gates are opened. The blood of Jesus! we shall march on, conquering and to conquer, so long as we can trust its power!
