One of the techniques in technical writing is to being with a summary of the rest of the document. We certainly see that technique employed in the book of Hebrews:
Hebrews 1: In the past God spoke to our ancestors through the prophets at many times and in various ways, 2 but in these last days he has spoken to us by his Son, whom he appointed heir of all things, and through whom also he made the universe. 3 The Son is the radiance of God’s glory and the exact representation of his being, sustaining all things by his powerful word. After he had provided purification for sins, he sat down at the right hand of the Majesty in heaven. 4 So he became as much superior to the angels as the name he has inherited is superior to theirs
We are blessed to be recipients of God’s plan for salvation and we will see this reality repeated several times during our study.
