And he causeth all, both small and great, rich and poor, free and bond, to receive a mark in their right hand, or in their foreheads: And that no man might buy or sell, save he that had the mark, or the name of the beast, or the number of his name. Here is wisdom. Let him that hath understanding count the number of the beast: for it is the number of a man(natural man); and his number is Six hundred threescore and six.
The Mark of God the Father
Revelation 14:1-5, And I looked, and, lo, a Lamb stood on the mount Sion, and with him an hundred forty and four thousand, having his Father's name written in their foreheads.
II Thessalonians 2:9-12
Even him, whose coming is after the working of Satan with all power and signs and lying wonders, And with all deceivableness of unrighteousness in them that perish; because they received not the love of the truth, that they might be saved. And for this cause God shall send them strong delusion, that they should believe a lie: That they all might be damned who believed not the truth, but had pleasure in unrighteousness.
And the nations of them which are saved shall walk in the light of it:
and the kings of the earth do bring their glory and honour into it.
When the bugle blows and we see Jesus in the clouds, He has come to take His children home.
The end of time here on earth will be over and only the ungodly will be left behind.
