John 16:11 (KJV)
“Of judgment, because the prince of this world is judged.”
Satan was Judged at the cross. Jesus said I beheld Satan fall as lightning from heaven. God calls those things which be not as though they are. Jesus was speaking prophetically of what would happen after the cross. Satan falls in three stages: in his first fall he lost his archangel status, in his second fall which we are speaking of now, he loses his heavenly access into the third heaven and is only relegated to the first heaven, and in his last fall he is cast into the lake of fire
Mark 3:27 (KJV) “No man can enter into a strong man’s house, and spoil his goods, except he will first bind the strong man; and then he will spoil his house.” Jesus spoiled his goods at the cross:
Colossians 2:15 (KJV) “And having spoiled principalities and powers, he made a shew of them openly, triumphing over them in it.”
“It meaning the cross) but how did Jesus have power over him before the cross? Because Christ was already ordained to die before The world began.
Jesus bound Satan first by casting him out of heaven so he couldn’t use the Old Testament law against the saints anymore so he shut the mouth of devil:
John 12:31 (KJV) “Now is the judgment of this world: now shall the prince of this world be cast out.”
Revelation 12:9 (KJV) “And the great dragon was cast out, that old serpent, called the Devil, and Satan, which deceiveth the whole world: he was cast out into the earth, and his angels were cast out with him.
Revelation 12:10 (KJV) “And I heard a loud voice saying in heaven, Now is come salvation, and strength, and the kingdom of our God, and the power of his Christ: for the accuser of our brethren is cast down, which accused them before our God day and night.”
By this being done by what Jesus did at the cross we have power over the works of the devil. Revelation 20 is key, this happened after the temple was destroyed in A.D . 70. Satan was bound FROM DECEIVING THE NATIONS, the nations meaning non Jews from being able to hear the gospel. People could believe on Jesus. The gospel would be proclaimed throughout the world which happened and is happening.
