Isaiah 66: 15-16: "For, behold, the LORD will come with fire, and with his chariots like a whirlwind, to render his anger with fury, and his rebuke with flames of fire. For by fire and by his sword will the LORD plead with all flesh: and the slain of the LORD shall be many."
This is the Lord working THROUGH His saints (purified believers that are dead to self--not milk bottle Christians; Lordship Christians, not salvation Christians). When the Lord glorifies your body (rapture, the Presence God, Holy Ghost Fire), this is how the Lord destroys Satanic strongholds: strongholds in our physical bodies; powers and principalities in the heavenlies.
The Lord glorifies my body (rapture) usually a few to several times a week. Sometimes it is so powerful, I think my eyes are going to burn right out of their sockets; it is almost painful.
II Thessalonians 1: 8-10: "In flaming fire taking vengeance on them that know not God, and that obey not the gospel of our Lord Jesus Christ: Who shall be punished with everlasting destruction from the presence of the Lord, and from the glory of his power; WHEN HE SHALL COME TO BE GLORIFIED IN HIS SAINTS [The Second Coming to purified believers--believers that have gone through their tribulation], and to be admired in all them that believe (because our testimony among you was believed) in that day."
