OK, I'm going to pull out all the stops. Here is why the coming Antichrist will be Satan himself, in person, here on earth, at the end just prior to Christ's return. For those who have a problem believing in things supernatural, you might want to go away, or cover your eyes or something.
1. in Ezekiel 28 & 31, and Isaiah 14, our Heavenly Father revealed how Satan originally sinned against Him in coveting His Throne. Through parable, we are shown that Satan was originally created a covering cherub (meaning his job was guarding the Mercy Seat of God's Throne), and he was originally created perfect in his ways. In other words, originally Satan served GOD, and was a good cherub. But then through his coveting he fell and iniquity was found in him. Our Lord Jesus was there, as He said He saw Satan as lightning fall from heaven (Luke 10:18). This all happened in a previous world age, even prior to Adam and Eve. One might call it an angelic world age that was before flesh man (2 Peter 3:5-6; Genesis 1:2).
2. God ended that old world age, because of Satan's rebellion. He then began this 2nd world age we are still in now, which is preserved unto destruction by fire (2 Peter 3:10). Our Lord Jesus was ordained to be born in the flesh through woman's womb to die on the cross for the remission of sins of those who believe on Him. His whole purpose in doing that we are told, was to defeat death and the devil for us (Hebrews 2:14; 1 John 3:8).
3. At the same time with God creating this 2nd world age, He placed His creation in a state of imperfection, in bondage to vanity (Romans 8:18-25). Even God's creation today is looking forward to the release from that bondage, along with us, with the future manifesting of the sons of God (i.e., pointing to the future new heavens and a new earth time). Thus, today's creation is imperfect, not how God originally created it. Satan's rebellion caused this 2nd world age of today, and is why God placed His creation in its state of bondage to corruption for today's world age.
4. in the time old, before Satan fell, he was over all great nations that existed on this earth before (meaning even prior to Adam). That was not a pre-Adamic flesh race nor anything like that. It was an angelic dwelling upon the old earth. In the Ezekiel 31 parable this is hinted at, before he fell. So ideas that this earth isn't very ancient are just tools used by Satan to keep the previous world age a secret. In Jeremiah 4:23-28, God reveals His anger with destroying that old earth of Genesis 1:1, and creating today's earth state beginning at Genesis 1:2 forward. And for this reason He said the earth would mourn, and the sky above would be black (i.e., storms from a faulty atmosphere around the earth).
5. In Genesis 2 with God's Garden of Eden upon this earth, that is to show that He once dwelt upon this earth, with His River of the Waters of Life, and the Tree of Life, all in His Garden of Eden. We are shown that His River flowed out of Eden to feed four other rivers upon the earth, two of which still exist today (Euphrates and Tigris). Genesis 3, after Adam fell, reveals God removing His Eden off of this earth to another dimension of existence, behind a veil, with flaming cherubim guarding the way to the Tree of Life. We are to especially grasp that His Abode was once upon this earth, literally. Thus the supernatural, for our Heavenly Father is Supernatural, a Spirit, can literally live and walk upon this earth. Like He said in Isaiah 45:18, He created this earth to be inhabited, and it always will be, for the meek shall inherit the earth.
6. For the end of this present world, God is going to allow Satan and his angels to try and play God once again, as he did in the beginning when he fell. This is the difference between the beast kingdom of only seven crowns shown in Revelation 12:3-4 when he drew a third of the stars (angels) into rebellion with him. The Revelation 13:1 beast kingdom for the end is to have ten crowns instead of seven. That is a direct parallel to the system Satan originally rebelled with in the previous world age before God destroyed that time.
7. some have difficulty with understanding the angelic. Our Lord Jesus said in the resurrection, they don't marry nor take in marriage, but are as the angels of God in heaven. He was saying the resurrection is an angel-like existence. It is of a different dimension than material matter. It is made up of Spirit instead, which our Heavenly Father is a Spirit. Forget the Hollywood movie junk, all that is only Satan's design to steer understanding away from what the spiritual actually is about. Our Heavenly Father has an outward Image Likeness like we do, and it is that of man (Gen.1:26-27). This is why angels in God's Word appear with the image of men (Gen.19; Acts 1). That image originates from God. The angels can eat our food and live and walk upon this earth. Hebrews 13 tells us to be mindful to entertain strangers, because some have entertained angels and didn't know it. That shows they can be walking around among us and we won't know it. So forget all the Hollywood hype about spirits and what-not. There's good angels, and there's bad angels, just as the same with people on earth, there is a division in the Heavenly also.
8. some in today's world have their spiritual eyes and ears closed so that they cannot understand The Gospel nor the previous events above. God has His Own time schedule for when all eyes and ears will be opened, everyone fully understanding. Only He can change who hears and sees and who doesn't. We can only plant seeds of His Truth as He gives us. He has assured us through His prophets and Apostles that all knees will indeed bow to Him and His Son. That is according to His timeline, not ours.
These events reveal just how much the things of this world and man's sufferings are worth, that the treasures of this world, man's great wealth and pride, are mere nothings in contrast to the world to come after God destroys this present world age.
