I believe the kingdoms of the world are both physical and spiritual. Satan has always played a part in mass human deception. After all he did come to steal, kill, and destroy. Ezekiel 28 is a great example of this. This proclamation is against a physical king who ruled the earth, and also the evil spirit that controlled him. Verse 13 says that he was in the garden of God, but yet he was a king that lived during Ezekiel's day. Another example of this is in Daniel 10:13 where Daniel had prayed for 21 days for an answer, but it was held up by the prince of Persia. Who is this prince of Persia? Would a physical human being be able to prevent an angel from getting to Daniel? I doubt it...this prince of Persia is more than likely a spiritual being (demon) who is controlling the kingdom of Persia via it king. Daniel 10:20 also mentions the prince of Greece. Again, this could mean a human, but probably is a demon over that area. Ezekiel when talking about Gog calls him a Chief Prince of Meshech and Tubal. But Revelation speaks of Gog again at the end of all things trying to gather an army after satan had been released from the bottomless pit.
Potential Spiritual Beings:
- Prince of Persia - Daniel 10:13
- Prince of Greece - Daniel 10:20
- Chief Prince of Meshech and Tubal (Turkey) Ezekiel 38:2-3
- Prince of Demons - Beelzebub - Matt 12:24
