God has given His final revelation in His Son (1:1-2a). The seven affirmations that immediately follow in the introduction to Hebrews bring out the greatness of the Son and show why the revelation in Him is the highest God can give (vv. 2b-4): He is the heir of everything and the mediator of creation, the radiance of God’s glory and the exact representation of His being, and so is uniquely qualified to be the final manifestation of God, for He is identified with God Himself. He has accomplished something that no one else could achieve, the purification of sins which occurred in His once-for-all death on the cross (7:27;10:12,12:2). Having completed the work of atonement, the Son has been exalted and enthroned in the place of honour, at the right hand of God. He is the divine Son who learned obedience by what He suffered and, once made perfect, became the author of eternal salvation for all who obey Him (5:5,8). Is it any wonder, then, that Jesus, the great High Priest who has passed through the heavens is triumphantly identified as ‘the Son of God’ in the confession of faith by believers (4:14-16)?
