What does the Bible say about the eternal nature of Christ's kingdom?

According to Scripture, Christ's kingdom is from everlasting, enduring throughout all time, and is to everlasting. This kingdom is established on the eternal covenant of grace, where all subjects were given to Christ as their Mediatorial King before the foundation of the world (John 6:37, John 10:11-14). The kingdom of Christ, unlike earthly kingdoms, is spiritual and internal, set in the hearts of believers and is not of this world (John 18:36). It is confirmed that Christ's dominion is everlasting, which shall not pass away, and His kingdom will remain long after the kingdoms of this world have ceased to exist (Daniel 7:13-14).
