Heb.5:5- So also Christ did not glorify Himself so as to become a high priest, but He who said to Him, “YOU ARE MY SON, TODAY I HAVE BEGOTTEN YOU”;
People tend to get weird and confused when you talk about Jesus as the eternal Son of God and at the same time being God Himself. The Muslims get all out of sorts when we talk about the Son of God. They think it is blasphemous to talk about God having a son. Humans want to understand the Son of God in natural terms, that is impossible. He is eternal yet begotten of the Father. He is God’s only Son who is begotten of the Father but has been with the Father from eternity. That was the mystery David touched on in this Psalm. In the following verse David called Him Melchezidek. Paul taught extensively about this in Hebrews. He said this was speaking of the the eternal nature of the Son of God. Melchezidek was without mother or Father and has an eternal existence. Here is some of Andrew Murray’s thoughts on today’s verse.
“The Son was not only begotten of the Father in eternity, but begotten again in the resurrection. In the incarnation the union between the divine and the human nature was only begun: it had to be perfected by Christ, in His human will, yielding Himself to God’s will even unto the death. In the resurrection, “He was declared to be the Son of God with power”; the full outbirth of humanity into the perfected fellowship and equality with Deity was completed; the Son of Man was begotten into all the likeness and glory of the Son of God. Thus Paul applies it “God raised up Jesus, as also it is written in the second Psalm, Thou art My Son, this day have I begotten Thee.” He then became the first begotten from the dead. And again, I will be to Him a Father, and He shall be to me a Son. The words were spoken to David of a son God should give to him, but with the clear indication that their meaning reached far beyond what any mere man could be. In the Son of Man, who in the resurrection was raised up in power, and declared to be the Son of God, they find their complete fulfilment.”
David’s prophesies about the Eternal Son and His heavenly ministry as our heavenly High Priest are quite profound. We have an advocate with the Father, Jesus the Eternal Son of God.
