'By their fruits you will know them'. It's got everything to do with characteristics.
Listen.
Let me explain the A. OF D>
There was a time that Satan was an anointed Cherub. A Cherub is a winged "higher authority" class of Heavenly Host.
You can find 2 of them, if you research any photo or illustration regarding the : "ARK of the Covenant'.
LUCIFER, became Satan, falling from Heaven, and Jesus said He saw Him fall as "lighting".
He is referred to as a "light bearer".. which means a "knowledge bringer".
This is why Paul refers to him as an "Angel of Light", but the light He brings is DARK Light, ...
And People who are ultra deceived by Him, who are Religious or even born again are : Luke 11:35.
In Heaven, Lucifer "fell" into sin in His heart, and "iniquity was found IN HIM.."
3 Of them.
Murder.
Father of Lies
And Pride.
The Pride was that He became so VAIN that He wanted to be not just be God, but be elivated on a Throne superior to God's.
Now, when he returns as the AntiChrist, The Beast, that begins the Trib, He is going to deceive most of the World into thinking that he is "Christ" and will be a religious leader, a "man of Peace".
ISLAM believes he is the Savior.......their
MAHDI
This will mark the beginning of the Trib, that is a 7 yr period that strictly followed the end of the "time of the Gentiles".
The second half of the Trib, is called the GREAT Trib, and at that time, Satan will on Earth proclaim Himself as what He was trying to DO, In heaven.
And that is the "Abomination of Desolation", and it will be VIEWED.. He will be seen doing it by everyone who was not born again in the "time of the Gentiles"....., as He will be in control of your SCREEN.
