Satan was thrown from Heaven and is the prince of this world. He offered Jesus all of the 1st & 2nd Heaven if Jesus would just bow to him, satan, just once. Jesus will come back and reclaim 1st & 2nd Heaven and banish satan and his fallen spirits forever

Why was Satan thrown from heaven? I did not know there were 3 heavens. Where is this heaven you speak of?

Satan [Lucifer] was thrown down from Heaven with 1/3 of the angels that aligned themselves with him. Lucifer, a created being, was the most glorious of all angels and very close to God. He became unsatisfied with his position and wanted to be equal with God. I ask, how can a created being ever be equal with its Creator? After a rebellion Lucifer & the 1/3rd were cast from Heaven.

Reference to 3 Heavens -

1st - Earth & its atmosphere [physical]

2nd - The area we call Outer space [physical]

3rd - God's dwelling place [spirutual]
