And I will put My spirit within you, and cause you to walk in My statutes, and ye shall keep My judgments, and do them. – Ezekiel 36:27

The coming of the Holy Ghost into the soul gives a mortal stab to the power of sin. The old man is not absolutely dead, but it is crucified with Christ. It is under sentence, and before the eye of the law it is dead; but as a man nailed to a cross may linger long, but yet he cannot live, so the power of evil dies hard, but die it must. Sin is an executed criminal: those nails which fasten it to the cross will hold it fast till no breath remains in it. God the Holy Ghost gives the power of sin its death wound. The old nature struggles in its dying agonies, but it is doomed, and die it must. But you never will overcome sin by your own power, nor by any energy short of that of the Holy Spirit. Resolves may bind it, as Samson was bound with cords; but sin will snap the cords asunder. The Holy Spirit lays the axe at the root of sin, and fall it must. The Holy Ghost within a man is “the Spirit of judgment, the Spirit of burning.” Do you know Him in that character? As the Spirit of judgment, the Holy Spirit pronounces sentence on sin, and it goes out with the brand of Cain upon it. He does more: He delivers sin over to burning. He executes the death penalty on that which He has judged. How many of our sins have we had to burn alive! and it has cost us no small pain to do it. Sin must be got out of us by fire, if no gentler means will serve; and the Spirit of God is a consuming fire. Truly, “our God is a consuming fire…”This is what the Spirit does, and it is by no means easy work for the flesh, which would spare many a flattering sin if it could. ~ C.H. Spurgeon
