When Christ and the devil had the war of the Cross, Satan thought he had won, wrong, there was no contest, Christ won hands down.
If we give a mind to Satan the war is between us and him, but if we have, the mind of Christ and "Christ in us the Hope of Glory," who has already won the war?
If Christ and the devil had a fight right now, who do you think would win. We are Satan proof.
Christ is to Satan like rat poison to a scrounging, sniffing rat.
We have the victory in Christ, if the devil comes to us it is only because the Father has allowed it to make us more like Christ, as He did with Paul, "My Grace is sufficient",
2 Corinthians 12:9 And he said unto me, My grace is sufficient for thee: for my strength is made perfect in weakness. Most gladly therefore will I rather glory in my infirmities, that the power of Christ may rest upon me.
