In Hebrews 1:1-4 the author contrasts two ways God communicates: through the prophets of the OT and through his Son. The revelation is far superior to the old method of communication because of the surpassingly great glory of the Son. He is the heir of all things, the creator of all, the brightness of the glory of the Father, who upholds all things. He is the one who made purification for sins and sat down at the right hand of the majesty on high.
