And in their mouth was found no guile: for they are without fault before the throne of God. -Revelation 14:5

Oftentimes the Lord also grants us to know what it is to overcome temptation, and so to break the head of the fiend. Satan allures us with many baits; he has studied our points well and he knows the weakness of the flesh: but many and many a time, blessed be God, we have foiled him completely to his eternal shame! The devil must have felt himself mean that day when he tried to overthrow Job, dragged him down to a dunghill, robbed him of everything, covered him with sores, and yet could not make him yield. Job conquered when he cried, “Though He slay me yet will I trust in Him.” A feeble man had vanquished a devil who could raise the wind and blow down a house, and destroy the family who were feasting in it. Devil as he is, and crowned prince of the power of the air, yet the poor bereaved patriarch sitting on the dunghill covered with sores, being one of the woman’s seed, through the strength of the inner life won the victory over him.

“Ye sons of God oppose his rage.
Resist, and he’ll be gone:
Thus did our dearest Lord engage
And vanquish him alone.”

Moreover, dear brethren, we have this hope that the very being of sin in us will be destroyed. The day will come when we shall be without spot or wrinkle or any such thing; and we shall stand before the throne of God, having suffered no injury whatever from the fall and from all the machinations of Satan, for are “they are without fault before the throne of God.” What triumph that will be! “The Lord will tread Satan under your feet shortly.” When He has made you perfect and free from all sin, as He will do, you will have bruised the serpent’s head indeed. ~ C.H. Spurgeon
