Yes, only God is qualified to reconcile man to Himself.
"To wit, that God was in Christ, reconciling the world unto himself, not imputing their trespasses unto them; and hath committed unto us the word of reconciliation."
2 Corinthians 5:18-19 NKJV
Now all things are of God, who has reconciled us to Himself through Jesus Christ, and has given us the ministry of reconciliation, [19] that is, that God was in Christ reconciling the world to Himself, not imputing their trespasses to them, and has committed to us the word of reconciliation.
Read the verse in context. There is nothing which says only God can reconcile people to himself. Only the Calvinists believe that. Are you and Right Divider are now Calvinists?
He was promised, because He already existed before He was sent.
"...who, although He existed in the form of God, did not regard equality with God a thing to be grasped, but emptied Himself, taking the form of a bond-servant, and being made in the likeness of men." Phil 2:6-7
"Being found in appearance as a man, He humbled Himself by becoming obedient to the point of death, even death on a cross." Phil 2:8
This is a key set of verses showing Jesus is not God. Notice that it says he was in the form of God - not he is God. How was he in the form of God? He was God's Son and had divine position and authority. The next phrase is a key phrase emphasized by Paul in Romans 5. Adam attempted to become equal with God which caused his downfall, while Jesus
did not regard equality with God a thing to be grasped. This obedience unto death would not redeem humanity if Jesus were God. Jesus being human was key.
Jesus humbled himself by not using his position for his own ends. This is why Satan offers him all the kingdoms of the world. This is a nonsensical temptation if Jesus is God. The temptation is very real for someone for someone who will die on a cross. Jesus had the position of the Son of God. He humbled himself by not taking advantage of this position and choosing to obey God and die on the cross.
"Therefore, since the children share in flesh and blood, He Himself likewise also partook of the same, that through death He might render powerless him who had the power of death, that is, the devil" Heb 2:14
God partook of flesh and blood. If Jesus was only a promise, then no one partook. You must already exist in order to partake of that which you had yet to share.
Hebrews 2:14-18 NLT
Because God’s children are human beings—made of flesh and blood—the Son also became flesh and blood. For only as a human being could he die, and only by dying could he break the power of the devil, who had the power of death. [15] Only in this way could he set free all who have lived their lives as slaves to the fear of dying.
[16] We also know that the Son did not come to help angels; he came to help the descendants of Abraham. [17] Therefore, it was necessary for him to be made in every respect like us, his brothers and sisters, so that he could be our merciful and faithful High Priest before God. Then he could offer a sacrifice that would take away the sins of the people. [18] Since he himself has gone through suffering and testing, he is able to help us when we are being tested.
The problem is that you're trying to fit "Jesus is God" into the Bible. The passage is clearing going out of its way to make sure everyone understands that Jesus is human and that he is not some divine being. As for the word "partook", you're reading far too much into it. Yes, God's promise had to be human. In that way the promise "partook".
"Let this mind be in you, which was also in Christ Jesus: Who, being in the form of God, thought it not robbery to be equal with God: But made himself of no reputation, and took upon him the form of a servant, and was made in the likeness of men: And being found in fashion as a man, he humbled himself, and became obedient unto death, even the death of the cross." Phil 2:5-8
In order for Jesus to take upon Himself the form of a bond servant and be made in the likeness of men, He had to of already been in existence, and He was... IN THE FORM OF GOD.
You quoted the same passage in a previous translation, my explanation remains the same.
Reminds me of:
None of them can by any means redeem his brother, Nor give to God a ransom for him—For the redemption of their souls is costly, And it shall cease forever—That he should continue to live eternally, And not see the Pit. - Psalm 49:7-9

That's Anselm's soteriology. There are other soteriologies out there. You might want to look around.
