For false Christs and false prophets shall rise, and shall show signs and wonders, to seduce, if it were possible, even the elect. Mk 13: 22 KJV.
This means that it is impossible to fool or dupe true disciples or believers.
These are the words of Jesus to His Apostles concerning the last days.
So say you?
Let me add a couple more verses and bold/underline some relevant phrases.
Revelation 13:8 KJV
And all that dwell upon the earth shall worship him, whose names are not written in the book of life of the Lamb slain
from the foundation of the world.
Revelation 17:8 KJV
The beast that thou sawest was , and is not; and shall ascend out of the bottomless pit, and go into perdition: and they that dwell on the earth shall wonder ,
whose names were not written in the book of life from the foundation of the world, when they behold the beast that was , and is not, and yet is .
notice that the Lamb slain at Calvary, IN TIME, is also the Lamb slain from the foundation of the world. At the beginning of time, or before the beginning of time, however one wants to look at it.
notice also that the book was written from the foundation of the world, at the same instance that eternity's lamb was slain.
this book was not populated with names in accordance with the elect's beliefs, faith, repentance, coming to Christ, and whatever it is that popular gospel preaching demands nowadays.
those names were there before the owner of those names even existed.
like Christ said, "no man comes to me UNLESS the Father draws him", and "my sheep hear my voice, and they know me, and I know them".
and to those who claimed Christ on the basis of their works for Him, did He not say, "I NEVER knew you" ?
addendum:
what is it that those whose names were not written in the Lamb's book of life from the foundation of the world will do ? according to ch. 17:8, the will WONDER.
