We know what it is to be fireproof, to be waterproof: but it is a greater thing to be proof against sin. It is possible to be so filled with the Spirit and presence of Jesus that all the shafts of the enemy glance off our heavenly armor; that all the burrs and thistles which grow on the wayside fail to stick to our heavenly robes; that all the noxious vapors of the pit disappear before the warm breath of the Holy Ghost, and we walk with a charmed life even through the valley of the shadow of death. The red hot iron repels the water that touches it, and the fingers that would trifle with it: and, if we are on fire with the Holy Ghost, Satan will keep his fingers off us, and the cold water that he pours over us will roll off and leave us unharmed: "for He that was begotten of God keepeth us, and that wicked one toucheth us not."

It is said that before going into a malarious region, it is well to fortify the system with nourishing food. So we should be fed and filled by the life of Christ in such a way that the evil does not really touch our life.
