The Devil is always on the job, tempting us to disobey the Lord. And though nobody can keep temptation from coming, we don't have to yield to temptation. God gives us enough sense by His Spirit to know the difference between what is good and what is bad, then He gives us a choice between good and evil, Himself and the Devil. The Devil cannot prevent us from choosing. That's the one thing we can do no matter what the Devil does--we can choose! We each have a will, and we can ignore him! "Submit yourself to God, resist the Devil, and he will flee from you!" (Jam.4:7)
It is impossible for the Devil to win over you unless you give in to him, for "greater is He that is in you than he that is in the World!" (1Jn.4:4) The only way he can win is if you quit, give up, give in, surrender or stop fighting. If you keep fighting you keep winning! So when the Devil tempts you to get down and discouraged, fight! Slam the door in his face and don't even listen to him!--Much less surrender! Then you won't have a chance to listen to or believe his lies!"
Give no place to the Devil!" (Eph.4:27) Hallelujah!
