It's a theological deduction that the devil, is God's devil. All of creation is cursed and fallen, including humans, animals, spirits, the cosmos, and all therein. Yet all of creation is subject to The Creator. From scripture, one discerns that the devil is on a chain, and the length of that chain is determined by God. Satan can't do anything he wants. Yet, because Adam disobeyed God in rebellion, and because all of humanity has since ratified Adam's decision, God continues to sustain Satan in existence allowing him to tempt us. In the Book of Job, Satan is given permission by God to attack Job, (Job 1:12). Yet Job looked at it differently. Job stated, "Though He (God) slay me, yet will I trust in Him," (Job 13:15). Job also stated, "The Lord gives, and the Lord takes away, blessed be the name of The Lord", (Job 1:21). So it is good that we recognize Satan's role in the affairs of men. But it is also good that we recognize we are culpable (guilty) for our own sin, and as such God has ordained that we are to suffer the repercussions of our sin. Though sin's consequences effect us here on earth, Christ's righteousness is imputed to Christians, and our sin is not imputed to us, it is forgiven. At the resurrection of all flesh, Christians will be actualized in their choice to believe in Christ for salvation. At that time the veil between God and man will be lifted, as God and man will live together in a new world where sin is no longer possible! "Well what about Satan," you say? The Bible says that Satan and his demons will be eternally quarantined in hell, along with all those who want nothing to do with God. This is the second death.
