How do we know Christ is King according to Scripture?

The New Testament clearly identifies Jesus Christ as King. He was born King, as indicated by the wise men who sought Him, asking, 'Where is He that is born King of the Jews?' (Matthew 2:2). Furthermore, during His trial, Jesus was mocked as King, and above His cross, the inscription read 'Jesus of Nazareth, the King of the Jews' (John 19:19). This acknowledgment by both humble seekers and authorities highlights the universal sovereignty of Christ. His kingship is further affirmed as He reigns over all creation, both the living and the dead, as described in Romans 14:9.
