19 and what is the immeasurable greatness of his power in us who believe, according to the working of his great might 20 which he accomplished in Christ when he raised him from the dead and made him sit at his right hand in the heavenly places, 21 far above all rule and authority and power and dominion, and above every name that is named, not only in this age but also in that which is to come; 22 and he has put all things under his feet and has made him the head over all things for the church, 23 which is his body, the fulness of him who fills all in all.
1 Timothy 6: 14-16
14 I charge you to keep the commandment unstained and free from reproach until the appearing of our Lord Jesus Christ; 15 and this will be made manifest at the proper time by the blessed and only Sovereign, the King of kings and Lord of lords, 16 who alone has immortality and dwells in unapproachable light, whom no man has ever seen or can see. To him be honor and eternal dominion. Amen.
And I saw, and behold, a white horse, and its rider had a bow; and a crown was given to him, and he went out conquering and to conquer. END
The imagery of Jesus as a King is found all over the New Testament, and is foreshadowed in the Old. Jesus also refers to the ‘Kingdom of Heaven’. Since, as Jesus says “the Kingdom of Heaven is at hand” then Jesus must be a King over the earth.
Some people object that if Jesus were the King, there would not be sin and evil in the world. This argument is easily overcome by understanding that some people choose to obey the King and some choose not to, just as secular authorities can be obeyed or disobeyed. Grace be with you,
