How do we know that Christ is king according to the Bible?

Christ's kingship is firmly established in Scripture, as seen when He responds affirmatively to Pilate’s inquiry about His identity as the king of the Jews. Jesus clarifies that His kingdom is not of this world, indicating His spiritual authority. This sovereignty is further affirmed by the Apostles, such as in 1 Timothy, which declares Him the King of kings and Lord of lords. His reign is characterized by righteousness, peace, and spiritual joy, affirming that His kingdom operates through divine grace rather than earthly politics.
