Long ago God spoke to the fathers by the prophets at different times and in different ways. In these last days, He has spoken to us by His Son. God has appointed Him heir of all things and made the universe g through Him. The Son is the radiance of God’s glory and the exact expression of His nature, sustaining all things by His powerful word. After making purification for sins, He sat down at the right hand of the Majesty on high. So He became higher in rank than the angels, just as the name He inherited is superior to theirs. – Hebrews 1:1-4 (HCSB)
The author of Hebrews opens his word of exhortation by affirming that the revelation of the past came through the prophets in various ways. But now, in these last days, his revelation has come to us by means of his Son. This sets up the hermeneutical method of the whole book of Hebrews. Rather than read this as a statement that God’s Son is a new spoken word of revelation, we must understand that the author of Hebrews is telling us that everything spoken by the Prophets is to be understood through the Son (Luke 24:27), who is the very Word of the Father.
The reason for this is that the Son fully reflects and represents his Father in every detail (Colossians 1:19). He is the radiance of his glory, that light which shows us the Father (John 1:4, 9, 18). He is the exact representation of the Father’s very nature, because in him the fullness of the Father’s nature dwells (Colossians 2:9).
This Word was appointed by the Father in eternity past to be the Father’s heir, and from the Father his glory was received (John 17:5, 22). The Word then entered time and took on our nature (John 1:14) so that he may obtain for us that which was already his, by his obedient suffering (Hebrews 5:8). Once his task was complete, he returned bodily to his Father’s side, where he reigns not only as the divine Son of God, but as the righteous Son of Adam, a name and status superior to the Angels (1 Corinthians 6:3).
