In Revelation 12:12, John warns of the increased activity of Satan during the end times:
> “Therefore rejoice, O heavens, and you who dwell in them! Woe to the inhabitants of the earth and the sea! For the devil has come down to you, having great wrath, because he knows that he has a short time.”
This verse reveals that Satan’s fury intensifies during the Great Tribulation because he is aware that his time is limited.
> II Chronicles 20:17:
> Ye shall not need to fight in this battle: set yourselves, stand ye still, and see the salvation of the LORD with you, O Judah and Jerusalem: fear not, nor be dismayed; to morrow go out against them: for the LORD will be with you.
> John 8:36:
> If the Son therefore shall make you free, ye shall be free indeed.
We are at war with the forces of Satan right now and the battle belongs to the Lord.
> Ephesians 6:12:
> For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places.
