Mark of the Beast precursor
Satan's time is almost up! He is leading as many to the Lake of Fire with him as he is able to deceive. During the Tribulation, people will KNOW without a doubt that the LORD is real and they will STILL rebel against Him unto their doom. They would rather be in torment forever then to bow their will to a precious loving Savior.
Revelation 9:20-21
And the rest of the men which were not killed by these plagues yet repented not of the works of their hands, that they should not worship devils, and idols of gold, and silver, and brass, and stone, and of wood: which neither can see, nor hear, nor walk: Neither repented they of their murders, nor of their sorceries, nor of their fornication, nor of their thefts.
