The heart is deceitful above all things, and desperately wicked: who can know it? – Jeremiah 17:9
Put on the whole armour of God, that ye may be able to stand against the wiles of the devil. – Ephesians 6:11
It is a good thing to look at your face in a mirror, but your face is not yourself—no mirror can show you yourself. There is a certain temptation which has an affinity to the evil within you and, should Satan bring that temptation near, you will see yourself to your horror and shame! There shall then look out of the window of your countenance a man whom you did not see when you looked in the glass, for you only saw the house he lived in! So ugly is he that he makes the very house he lives in look horrible! When the angry man comes up and is visible to the naked eye, how he deforms the countenance! When obstinate old Adam comes to the window, what a dark forbidding face he wears! When that envious spirit comes up, what an evil glance there is in the eye! When the unbelieving spirit peers through the lattice, what a miserable countenance he shows compared with the face of faith and childlike confidence in God!
There is nobody in this world, dear Brothers and Sisters, that you have so much cause to be afraid of as yourself! Augustine used to pray, “Lord, deliver me from that evil man, myself.” A very appropriate prayer for a woman, too— “Lord, save me from myself.” If you are saved from yourself, you will be saved from the devil—for what can the devil do unless self joins hands with him in unholy league? But, oh, what watchfulness it will need! Here is room for faith, indeed! Faith does not decline the conflict nor puff us up with the notion that the fight is over—on the contrary, it takes to itself the whole armor of God because it sees the battle to be still raging! Faith is needed to be the shield to keep off the fiery darts and the sword with which to smite the foe.
