And The Lord God says this specifically as a warning at the end of the book,
Revelation 21
5 Then He who sat on the throne said, “Behold, I make all things new.” And He said [
b]to me, “Write, for these words are true and faithful.”
6 And He said to me, “It[
c] is done! I am the Alpha and the Omega, the Beginning and the End. I will give of the fountain of the water of life freely to him who thirsts. 7 He who overcomes [
d]shall inherit all things, and I will be his God and he shall be My son.
8 But the cowardly, [e]unbelieving, abominable, murderers, sexually immoral, sorcerers, idolaters, and all liars shall have their part in the lake which burns with fire and brimstone, which is the second death.”
Revelation 22
6 Then he said to me, “These words
are faithful and true.” And the Lord God of the [
b]holy prophets sent His angel to show His servants the things which must shortly take place.
7 “Behold, I am coming quickly! Blessed
is he who keeps the words of the prophecy of this book.”
8 Now I, John, [
c]saw and heard these things. And when I heard and saw, I fell down to worship before the feet of the angel who showed me these things.
9 Then he said to me, “See
that you do not
do that. [
d]For I am your fellow servant, and of your brethren the prophets, and of those who keep the words of this book. Worship God.”
10 And he said to me, “Do not seal the words of the prophecy of this book, for the time is at hand. 11 He who is unjust, let him be unjust still; he who is filthy, let him be filthy still; he who is righteous, let him [e]be righteous still; he who is holy, let him be holy still.”
Jesus Testifies to the Churches
12 “And behold, I am coming quickly, and My reward
is with Me, to give to every one according to his work. 13 I am the Alpha and the Omega,
the [
f]Beginning and
the End, the First and the Last.”
14 Blessed
are those who [
g]do His commandments, that they may have the right to the tree of life, and may enter through the gates into the city.
15 [h]But outside are dogs and sorcerers and sexually immoral and murderers and idolaters, and whoever loves and practices a lie.
16 “I, Jesus, have sent My angel to testify to you these things in the churches. I am the Root and the Offspring of David, the Bright and Morning Star.”
--------------------
v9, the angel says let them remain as they are at the end of the age. God will send on them a strong delusion to believe the lie. The time of the end is one of great delusion and deceptions and bad things happening to the world. This is the judgment of God on the wicked of the end of the days.
In other words, God will not grant to them repentance to believe and know the truth.
2 Thessalonians 2
5 Do you not remember that when I was still with you I told you these things? 6 And now you know what is restraining, that he may be revealed in his own time. 7 For the [
d]mystery of lawlessness is already at work; only [
e]He who now restrains
will do so until He is taken out of the way. 8 And then the lawless one will be revealed, whom the Lord will consume with the breath of His mouth and destroy with the brightness of His coming. 9
The coming of the lawless one is according to the working of Satan, with all power, signs, and lying wonders, 10 and with all unrighteous deception among those who perish, because they did not receive the love of the truth, that they might be saved. 11 And for this reason God will send them strong delusion, that they should believe the lie, 12 that they all may be condemned who did not believe the truth but had pleasure in unrighteousness.
