Where in the bible does it say the earth belongs to Satan, or if it says it or anything close to it?
Answer
The closest thing I can find to scriptures saying the earth belongs to Satan are some passages in the gospel of John that refer to “the prince of this world.” (John 12:31; 14:30; 16:11) They don’t specify who the prince is, but the implication is that it is a spiritual being conquered by the death of Christ, hence Satan.
Those passages, along with the book of Revelation, indicate that Satan’s power as prince of this world ended at the resurrection of Jesus. That is not to say he has no power now. “Be sober, be vigilant; because your adversary the devil, as a roaring lion, walketh about, seeking whom he may devour.” (1 Peter 5:8) It just means that the power he had over man by the fear of death is no more, because we no longer need to fear the judgement.
So, the earth may have once belonged to Satan. It does so no more.
