When did Christ defeat Satan? Well, it was predicted immediately after the fall in the third chapter of the Bible, when it says Christ will “bruise [Him] on the head” (Gen. 3:15). 1 John 3:8, “The Son of God appeared for this purpose, to destroy the works of the devil” (cf. Jn. 12:31). We see this victory ultimately happen through His Passion when our Savior defeated the devil and dealt Him a mortal wound. Hebrews 2:14, “That through death He might render powerless him who had the power of death, that is, the devil.” Colossians 2:15, “When He had disarmed the rulers and authorities, He made a public display of them, having triumphed over them through Him.” And then He, 1 Peter 3:22, ascended to “the right hand of God, having gone into heaven, after angels and authorities and powers had been subjected to Him.” The war is over. The mission is completed. Satan is defeated. And while he still, 1 Peter 5:8, “Prowls around like a roaring lion, seeking someone to devour,” his ultimate defeat is guaranteed. Romans 16:20, “The God of peace will soon crush Satan under your feet.” Revelation 20:10, “And the devil who deceived them was thrown into the lake of fire and brimstone, where the beast and the false prophet are also; and they will be tormented day and night forever and ever.”
