Comment:

The sonship of Jesus was predetermined in the mind and plan of God from eternity, but he did not really exist until he was born in Bethlehem.  As my mentor Robert Sabin described, when a homebuilder looks at blueprints of his future home, they see the plans for the bathroom and say, "There's the bathroom."  They can see it in their mind's eye, but it doesn't exist yet.  The plan of Jesus' birth, life, sacrifice, and death was similar. You might say, God had a blueprint of salvation that was so real to him he could see it as though it already existed.  Romans 4:17 tells us "God...calls things that are not as though they were."  Psalm 2:7 (quoted above) in the KJV states "this day have I begotten thee." Jesus was God's son, his only son—he had a birthday which means there was a time when he did not exist.    The spirit of God is eternal, without beginning or end.  Man is not eternal.  As a man, Jesus  had a beginning.  The humanity of Jesus died as a sacrifice for our sins at Calvary.   The spirit of the risen Christ, humanity and divinity together will never end.  Since the first Christmas day, Jesus will always be God, and God will always be man.  1 Corinthians 15:28 describes a time when "God will be all, and in all."  The sonship of Jesus as mediator to the human race will no longer be necessary when there is no more sin, no more death, no more sorrow.  Jesus will always be God's only begotten son.
