Jesus Christ is presented in Scripture as a Prophet, a Priest, and a King.
As Prophet, He tells men what God has to say to them, and He reveals God to men. John 1:18
As Priest, He represents believers before God. Hebrews 4:14-16.
As King, He reigns today in the hearts of those who are loyal to Him (who trust in Him as Lord and Savior). In the coming day, He will reign upon the earth for one thousand years (Revelation 20:2-3). Psalm 72 describes His reign on earth. Thereafter, Jesus will continue to be our King of Kings and Lord of Lords throughout eternity.
