Is this a trick question?
Are you really serious?
Yes, it is a serious question! Since before his binding Satan had power to hold the Gentile nations of the world in bondage to sin and death, how can any Gentile be saved if Satan was not bound through the advent of Christ's cross and resurrection? Those who believe Satan has not yet been bound through the power of Christ's cross & resurrection must explain how Gentiles, of which number an "innumerable multitude" from all the nations of the world have been and are being saved as the gospel of the Kingdom of God has been and is being proclaimed unto all the nations of the world.
This verse tells us Satan had power to deceive "the nations" before being bound! Since the advent of Christ's cross and resurrection that deception is broken for Gentiles (the nations) who hear the gospel of the Kingdom of God and believe on Christ for eternal life.
Revelation 20:3 (KJV) And cast him into the bottomless pit, and shut him up, and set a seal upon him,
that he should deceive the nations no more,
till the thousand years should be fulfilled: and after that he must be loosed a little season.
Why is Satan's power limited to deceiving the "nations" (Gentiles) and not Israel also?
Since Christ's cross and resurrection spiritually binds Satan, the gospel of the Kingdom of God has been proclaimed, and "ALL nations", no longer the nation of Israel alone, but "ALL NATIONS" are numbered among the elect of God, standing, spiritually speaking, before the Lamb, clothed in white, symbolizing having righteousness of Christ resting upon them. How? By grace through faith in the cross and resurrection of Christ, they are no longer being deceived, no longer bound by power Satan held over them through fear of sin and death. In Christ sins are forgiven and we no longer fear death because the life we receive through the advent of Christ shall NEVER end.
Revelation 7:9 (KJV) After this I beheld, and, lo,
a great multitude, which no man could number, of all nations, and kindreds, and people, and tongues, stood before the throne, and before the Lamb, clothed with white robes, and palms in their hands;
