The beast which was and is not, is himself also an eighth and is one of the seven, and he goes to destruction. The ten horns which you saw are ten kings who have not yet received a kingdom, but they receive authority as kings with the beast for one hour. These have one purpose, and they give their power and authority to the beast. These will wage war against the Lamb, and the Lamb will overcome them, because He is Lord of lords and King of kings, and those who are with Him are the called and chosen and faithful. Revelation 17:11–14, NASB
There are three attributes of those who belong to Christ. No one else has these attributes. We see them in Revelation 17:14. Those with Christ, the Lamb who will conquer all His enemies for He is Lord of lords and King of kings, are called and chosen and faithful. In Matthew 22:1–14, our Lord tells a parable called “The Parable of the Wedding Feast.” In it our Lord describes the consequences that will befall those who believe their religiosity or position in the visible church is what earns them a place in the Kingdom, but who, in reality, are not among the chosen.
