To be "slain by his sword" or as Paul says "falling away"

When the king of Babylon of Revelation arrives here in person (Rev. 12:7-9)
there will be only one group of people who will not be "slain by his sword",
i.e. deceived into believing he is Jesus Christ and worshipping and serving him.

That group are those men and women who have the Seal of God,
His Word, in their foreheads [brains](Rev. 9:4).

All others will be spiritually slain because all others have the Seal of Satan,
deception, in their foreheads [brains].
In Revelation this seal of deception is called the mark of the beast.

There is only one way to avoid being slain by the beast
and to acquire the Seal of God in your mind,
and that is to "eat the scroll", study His Word, and "digest it in your bowels",
i.e. absorb it in your mind with understanding.

We are about to read in Ezekiel 33, is that there are no "good deeds" or "righteous acts"
that will prevent your slaughter (spiritually) by the king of Babylon.

If you are Biblically illiterate and ignorant of God's Word,
you are simply not "sealed" and you WILL BE deceived by Satan.

It is written!

It is your choice.

Therefore repent and stop listening to the traditions of men
and study His Word and then,
unlike those in the last few verses of this chapter,
DO THEM.

Well, you just read that no matter how righteous a person thinks he is
(for if they do not study His Word they are disobedient children and are displeasing Him)
if he is Biblically illiterate and ignorant of God's Word
and therefore not "sealed" in his forehead,
all his "goodness" and "righteousness" alone will not prevent him from "falling away"
and worshipping antichrist when he shows up.

That is the great apostasy spoken of by Paul in 2 Thes. 2:3,
"Let no man deceive you by any means:
for that day shall not come, except there come a falling away first,
and that man of sin be revealed, the son of perdition;

That "falling away" is to be "slain by the sword" of the king of Babylon,
i.e. deceived into believing that the son of perdition is Jesus Christ.
