Yes, Jesus will be referred to as a "mighty god", for he has great power ("mighty") and wisdom ("wonderful counselor"), he is the Prince of Peace and he will establish peace on the Earth, and he is the father of eternity (literal translation, not "eternal father") - through Jesus we will have eternal life. But he will not be referred to as the "almighty God", who is our heavenly Father, Yahweh.
Do you really think that God, Yahweh, could humble Himself? The definition of humble is "someone who knows they are not perfect; having or showing a consciousness of one's defects or shortcomings" (from
Humble Meaning | Best 16 Definitions of Humble), or "having a feeling of insignificance, inferiority, subservience, etc." (from
Definition of humble | Dictionary.com). Who would God humble Himself to? Jesus, on the other hand, humbled himself before God, his Father, and became God's servant, doing only what God told him to do, including sacrificing his own life.
In Acts 2 (WEB) Peter said:
22) “Men of Israel, hear these words! Jesus of Nazareth, a man approved by God to you by mighty works and wonders and signs which God did by [
through] him among you, even as you yourselves know,
23) him, being delivered up by the determined counsel and foreknowledge of God, you have taken by the hand of lawless men, crucified and killed;
24) whom
God raised up, having
freed him from the agony of death, because it was not possible that he should be held by it.
You look at the flesh that was necessary for God to come among us, so that his fleshly body could pay the ransom for our sins. This is something a sheep of lamb cannot do, it needs a perfect sinless man.
25) For David says concerning him, ‘I saw the Lord always before my face, For he is on my right hand, that I should not be moved.
26) Therefore my heart was glad, and my tongue rejoiced. Moreover my flesh also will dwell in hope;
27) because you will
not leave my soul in Hades,
neither will you allow your Holy One to see decay.
28) You made known to me the ways of life. You will make me full of gladness with your presence.’
[Peter quotes from Psalm 16, a prayer of David to Yahweh, and applies it to Jesus.]
29) “Brothers, I may tell you freely of the patriarch David, that he both died and was buried, and his tomb is with us to this day.
[i.e. David's body has seen decay.]
30) Therefore, being a prophet, and knowing that God had sworn with an oath to him that of the fruit of his body, according to the flesh, he would raise up the Christ to sit on his throne,
31) he foreseeing this
spoke about the resurrection of the Christ, that his soul wasn’t left in Hades, and his flesh didn’t see decay.
32)
This Jesus God raised up, to which we all are witnesses.
[If God, Yahweh, raised up Jesus then Jesus cannot be God.]
33) Being therefore
exalted by the right hand of God, and having received from the Father the promise of the Holy Spirit, he has poured out this, which you now see and hear.
[Jesus, God's only begotten son, has been exalted by God. God can't exalt Himself!]
34) For David didn’t ascend into the heavens, but he says himself, ‘The Lord said to my Lord, “Sit by my right hand,
35) until I make your enemies a footstool for your feet.”’
[From Psalm 110:1 (WEB): Yahweh says to my Lord, “Sit at my right hand, until I make your enemies your footstool for your feet.”]
36) “Let all the house of Israel therefore know certainly that God has made him both Lord and Christ, this Jesus whom you crucified.”
