“ Long ago, at many times and in many ways, God spoke to our fathers by the prophets,  but in these last days he has spoken to us by his Son, whom he appointed the heir of all things, through whom also he created the world.”Hebrews 1:1-2 ESV
The first verse here presses to the mind the awesome reality that God has spoken! It does so however with a very important qualification, that God speaks through His own appointed mediators. The varying accounts recorded in Old Testiment times were interpreted through the lense of such prophets. So history for God’s chosen people has always had theology as its primary emphasis. For sure, to the 1st century Jew, the events of the Old Testement were ancient history but they had the written word of these accounts passed down to them and they considered the texts revelation from God; Jesus himself held men accountable to those very texts as those who have heard from God through them.
Verse 2 then draws finality and closure to what is to be revealed from God when it tells us that a greater mediator has been given, The Son. Jesus is understood by the author here to have spoken to God’s chosen people again, in great display, after a long period of silence, in what is framed in the context of “these last days.” God’s revelation gets closure when Christ is done teaching us about His Father who sent Him.
God appointed Christ “heir of all things.” Instantly, the scripture commands that the relationship between the persons of the trinity come to the mind. The Godhead has determined that all things are for Christ, the Son has been appointed such a global and universal inheritance of glory that is hard to fathom. This assertion that all things have their purpose in this appointment is addressed in the very same sentence that states the Son also created the world. If anyone would credit this inheritance appointment due to the actions of Christ in time as we creatures know it, they miss that the appointment to inherit all things written of comes before His incarnation, it was planned from before the foundation of the world. The context here is that the Son was with the Father when the Father made the world through the Son. For certain, the actions Christ performed on earth revealed the glory due His name but that glory He kept vailed in the form of a suffering servant who would go to a cross and suffer wrath on behalf of His elect. The greatest truly became the least and will forever be praised as the greatest by those He saved in the process.
Christ is the ultimate purpose for creation and verse 2 here teaches that before time began for the creatures in God’s creation, this purpose was settled among the three persons of the trinity – creation is to be the theater where the Father unfolds the reality of this inheritance appointment to the Son.
