“God, who at various times and in various ways spoke in time past to the fathers by the prophets, has in these last days spoken to us by His Son, whom He has appointed heir of all things, through whom also He made the worlds; who being the brightness of His glory and the express image of His person, and upholding all things by the word of His power, when He had by Himself purged our sins, sat down at the right hand of the Majesty on high” (Hebrews 1:1-3 NKJV)

This Hebrews passage is one of the four pillars of Christology (John 1, Phil. 2, and Col.1 are the other three). Here, we see His threefold office of Prophet, Priest and King revealed.
1) Prophet: “spoken to us by His Son.” He is God’s ultimate, supreme and final revelation.
2) Priest: “purged our sins.” He is both God’s great high priest and perfect sacrifice.
3) King: “heir of all… made the worlds… brightness of His glory… express image… upholding all… right hand of Majesty.” He is owner, creator, God of very God, sustainer and king.
This is whom we have believed and received. This is our Redeemer and Friend, Jesus Christ. There is no other name by which we may be saved (Acts 4:12). Worship Him!
