As we've already seen, Satan appears twice on earth, first through the Catholic Church and second through the Church of God. Thus, the beast coming up out of the sea witnessed in Revelation 13:1 prophesied Catholicism, and the second beast witnessed in verse 11 prophesied the Church of God. The second beast builds an idol for the first beast, Catholicism (spiritual Babylon, Lucifer), which in turn builds an idol for Lucifer. Since Lucifer was an angel who ruled Babylon and the Catholic Church fulfilled Babylonian prophecy, the second beast making an idol for the first beast was God showing them that they would make an idol for Lucifer. The second beast gives people the mark of 666, the number of Satan, which scholars interpret as a bar code or the Catholic Church, but that's wrong. Bible prophecy is found in the Bible, not outside of it.

To understand 666, the mark of Satan, we must study the first beast well. Since the first beast prophesied Catholicism, and Catholicism fulfilled the prophecy of spiritual Babylon, we must study the history of Babylon to discover the reality of 666. Nebuchadnezzar, king of Babylon, had a dream about a giant statue made of gold, silver, brass, and iron, and built it out of gold to symbolize Babylon, the eternal empire.

[ Daniel 3:1] Nebuchadnezzar the king made an image of gold, the height of which was sixty cubits and its width six cubits; he set it up on the plain of Dura in the province of Babylon.

Nebuchadnezzar erected a giant golden statue 60 cubits high and 6 cubits wide and had those who did not bow down to the statue put to death, and you may notice that the size of the statue is similar to 666, the number of Satan. So where do we find the hidden 600?

In the Temple of God that Solomon built, the dimensions of the Holy of Holies were 20 cubits long by 20 cubits wide by 20 cubits high, which adds up to 60 cubits, and the total amount of gold that went into it was 600 talents. By the way, the overall length of the Holy of Holies, 60 cubits, matches the height of the golden statue that Nebuchadnezzar made, 60 cubits. So we can see that the total amount of gold used to make the statue is the same as the total amount of gold used in the Holy of Holies.

[2 Chronicles 3:8] Now he made the room of the holy of holies: its length across the width of the house was twenty cubits, and its width was twenty cubits; and he overlaid it with fine gold, amounting to 600 talents.

So Nebuchadnezzar used 600 talents of gold to create an enormous statue of the god, 60 cubits high and 6 cubits wide, which would be the substance of Satan's mark, 666. Nebuchadnezzar built a statue of a god with the dimensions of 666 for the eternal Babylonian empire and made them die if they did not bow down to it, which showed that the Church of God, which appeared as the reality of Lucifer, would do the same thing. For his eternal rule, Kim Ju-cheol set up two idols, Ahn Sang-hong and Jang Gil-jah, and brainwashed people to worship them, killing their souls.

[Revelation 13:15~18] And it was given to him to give breath to the image of the beast, so that the image of the beast would even speak and cause as many as do not worship the image of the beast to be killed. And he causes all, the small and the great, and the rich and the poor, and the free men and the slaves, to be given a mark on their right hand or on their forehead, and he provides that no one will be able to buy or to sell, except the one who has the mark, either the name of the beast or the number of his name. Here is wisdom Let him who has understanding calculate the number of the beast, for the number is that of a man; and his number is six hundred and sixty-six.

Kim Joo-cheol had people receive the mark of 666 on their foreheads and hands, which means he brainwashed them to worship two idols, Ahnsahnghong and Jang Gil-jah, as God, and only those who received the mark were bought and sold, which means he proselytized to buy and sell people's souls (Revelation 18:13).

Just as God's people are led by God's right hand to preach the word (Isaiah 41:10), believers who receive the mark of 666 on their right hand will be led by evil spirits to preach, and just as God's name is written on the foreheads of God's people (Revelation 14:1), the names of Ahnsahnghong and Jang Gil-jah will be written on the foreheads (minds) of those who receive the mark of 666. Therefore, Satan, who appeared at the end of the world according to the prophecy of Antiochus IV, prophesied the Church of God's Kim Joo-cheol.
