“The ten horns which you saw are ten kings who have received no kingdom as yet, but they receive authority for one hour as kings with the beast. These are of one mind, and they will give their power and authority to the beast. These will make war with the Lamb, and the Lamb will overcome them, for He is Lord of lords and King of kings; and those who are with Him are called, chosen, and faithful.” Revelation 17:12-14
Notice that Jesus Christ will overcome the Beast (Satan) in the final conflict, and those who are with Him are “called, chosen and faithful.”
You must meet all three conditions to be with Jesus during this final conflict. Jesus said that “… many are called, but few chosen.” Those willing to lay down their lives are called and chosen to serve Christ. Once you are called and chosen, you must be faithful.
