In verse 2 "but in these last days he has spoken to us by his Son, whom he appointed heir of all things, and through whom he made the universe."
a)"..but in these last days he has spoken to us by his Son"..
God Himself spoke by this 'Son',through this 'Son', using his physical mouth and his physical body to relay His message AS Himself (the Son as God the Father) therefore divinity of the Father is also revealed in the Son, and how divine He (the Son) is indeed! As much divine as the Father!!
"..whom he appointed heir of all things.."
God Himself appointed Jesus to be THE HEIR of ALL things, and that includes EVERYTHING, the heavens and earth,the entire universe, and everything within it, including you and me..Thank God for that because we are His.
Actually this makes me wonder whether 'the heir of all things' also include the negative sides of 'the all thing' i.e. the earth: pollution, dying earth etc; humanity: pain,suffering, poverty, SIN..etc,etc..that's a question for everyone
As I ponder upon it, I think " all things" in this verse did mean ALL THINGS, the good AND the bad..which is why He who inherits also is He who has to die once and for ALL , so that after the ultimate sacrifice, what He inherits will be what He has done..the fruit of His work on the cross.And a "new heaven and a new earth, for the first heaven and the first earth had passed away.."
Another reason for Him being divine; He is the Prince of God!! the ruler of the present and the future heaven and earth.
c)"..through whom he made the universe.."
God made the universe through Jesus, His Son. God imparted His power into and through Jesus, power unimaginablely great that the whole universe is created..He is Divine Power in Himself indeed!!
verse 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
The role of the Son in doing the Father's will:
a) the body/mouth of God
the heir of all things - hence the cross and the reward-THE inheritance
c) the Power of God
d) the radiance of God's glory
e) sustainer of all things
f) puryfying sins by His death on the cross
