Just a refresher on the JW explanation of the what number 666, The Mark of the Beast, really means:
The Mark Identified
Immediately after disclosing the number 666, Revelation mentions 144,000 followers of the Lamb, Jesus Christ, who have his name and the name of his Father, Jehovah, written on their foreheads. These names identify the bearers as belonging to Jehovah and to his Son, about whom they proudly bear witness. Likewise, those having the mark of the beast proclaim their servitude to the beast. Thus, the mark, whether on the right hand or on the forehead, figuratively speaking, is a symbol that identifies its bearer as one who gives worshipful support to the beastlike political systems of the world. Those having the mark give to “Caesar” that which rightly belongs to God. (Luke 20:25; Revelation 13:4, 8; 14:1) How? By giving worshipful honor to the political state, its symbols, and its military might, to which they look for hope and salvation. Any worship that they render the true God is merely lip service.
In contrast, the Bible urges us: “Do not put your trust in nobles, nor in the son of earthling man, to whom no salvation belongs. His spirit goes out, he goes back to his ground; in that day his thoughts do perish.” (Psalm 146:3, 4) Those who heed that wise counsel are not disillusioned when governments fail to deliver on their promises or when charismatic leaders fall from grace.—Proverbs 1:33.
This does not mean that true Christians sit back and do nothing about mankind’s plight. On the contrary, they actively proclaim the one government that will solve mankind’s problems—God’s Kingdom, which they represent.—Matthew 24:14.
