Would you please help me with the understanding of Ps 2:7. There are those that teach that there is no eternal sonship and then this verse is quoted. I believe that our Lord Jesus was the Word and that the Word was with God and the word was God. This Word became flesh and dwelt amongst us. That all things were created by Him and for Him. The Bible also teaches that He was before all things and by Him all things consist. Does this verse refer to a time when the Father defined the role of the Son or is there another meaning?
Psalm 2:7 reads: “I will proclaim the decree of the LORD: He said to me, “You are my son; today I have become your father.”
The role of the Son in the trinity seems to have been defined by the Father to have a beginning and an end. The Hebrew word translated “today” or “this day” in Psalm 2:7 indicates that although the second member of the trinity is an eternal being His identification as the Son of God took place on a particular day. But even though that day began for us with His conception, the decision was made before the creation of the world. In 1 Peter 1:20 we read, “He was chosen before the creation of the world, but was revealed in these last times for your sake.” And speaking of the Son, Micah 5:2 tells us His origins (goings out) are from of old, from ancient times (from days of eternity).
Paul agreed with these prophecies and with John 1:1 about the Son being present with the Father at the Creation saying, “The Son is the image of the invisible God, the firstborn over all creation. For by him all things were created: things in heaven and on earth, visible and invisible, whether thrones or powers or rulers or authorities; all things have been created by him and for him. He is before all things, and in him all things hold together” (Colossians 1:15-17).
Another Psalm tells us when the end of this special assignment will take place.
“The LORD (Father) says to my Lord (Son): Sit at my right hand until I make your enemies a footstool for your feet” (Psalm 110:1).
I understand 1 Cor. 15:24-28 to be an expansion of this verse and a description of the event that will bring His role as the Son of God to a conclusion at the end of the Millennium.
“Then the end will come, when he hands over the kingdom to God the Father after he has destroyed all dominion, authority and power. For he must reign until he has put all his enemies under his feet. The last enemy to be destroyed is death. For he “has put everything under his feet.” Now when it says that “everything” has been put under him, it is clear that this does not include God himself, who put everything under Christ. When he has done this, then the Son himself will be made subject to him who put everything under him, so that God may be all in all.”
