1 Corinthians 6:2-3
Or, do you not know that God's people will judge the world? [Note: Possibly this refers to Christians somehow assisting Christ on the judgment day]. And if the world is [to be] judged by you [at that time], are you not capable of judging small matters [now]?
Revelation 3:21
The person who has victory [in the Christian life], I will grant him [the privilege of] sitting down with me on my throne, as I also had victory and sat down with my Father on His throne.
Revelation 17:14-16
These kings and the beast will wage war against the Lamb, and the Lamb will conquer them, for He is the Lord of lords and the King of kings. And those who are called and chosen [by God], and who are faithful [to Him will share the victory] with the Lamb."
