Very good response. If Jesus Christ was made in the likeness of man he had to have a human nature. Certainly God could not lay aside His nature! Therefore two natures!
Perhaps you are confusing the "form" with the "nature."
Form indicates that he took upon Himself human attributes: feel, have empathy, hunger, thirst, be tired, .... yet without the sin nature. That is He was as Adam in the garden before Adam willingly took what he knew he should not take.
The nature of Christ being "equal with God" was not given up, and was not in anyway diminished by taking on the "form" of Humanity.
Consider the Scriptures where it says, "Beloved, now
are we the sons of God, and it
doth not yet appear what we shall be: but we know that, when he shall appear,
we shall be like him; for
we shall see him as he is."
What form was Christ before the earthly ministry? Equal with God
What form was Christ while on earth? He was in human form, yet equal with God. ("I and the Father are one." "This is my son ...")
What form is Christ? In human form, Equal with God.
There are those who would interchange "form" and "nature."
The Word did not change natures when "formed" (in cased) in human. The Word still had all the nature (authority and power) of God, yet He was in the flesh.
And for those who would apply a "two nature" thinking to the Nicene Creed, here is an english translation that shows no difference in that statement and what I have stated.
Nicene Creed:
And in one Lord Jesus Christ, the only-begotten Son of God, begotten of the Father before all worlds; God of God, Light of Light, very God of very God; begotten, not made, being of one substance with the Father, by whom all things were made.
Who, for us men and for our salvation, came down from heaven, and was incarnate by the Holy Spirit of the virgin Mary, and was made man
The Athanasian Creed
But the Godhead of the Father, of the Son, and of the Holy Spirit is all one, the glory equal, the majesty co-eternal.
Such as the Father is, such is the Son and such is the Holy Spirit.
The Father uncreated, the Son uncreated, and the Holy Spirit uncreated.
The Father incomprehensible, the Son incomprehensible, and the Holy Spirit incomprehensible.
The Father eternal, the Son eternal, and the Holy Spirit eternal.
And yet they are not three eternals, but one eternal.
As also there are not three uncreated nor three incomprehensibles, but one uncreated and one incomprehensible.
So likewise the Father is almighty, the Son almighty, and the Holy Spirit almighty;
And yet they are not three almighties, but one almighty.
So the Father is God, the Son is God, and the Holy Spirit is God;
And yet they are not three Gods, but one God.
So likewise the Father is Lord, the Son Lord, and the Holy Spirit Lord;
And yet they are not three Lords, but one Lord.
London Baptist Confession of Faith 1689.
The Son of God, the second person in the Holy Trinity, being very and eternal God, the brightness of the Father's glory, of one substance and equal with him who made the world, who upholdeth and governeth all things he hath made, did, when the fullness of time was come, take upon him man's nature, with all the essential properties and common infirmities thereof, yet without sin; being conceived by the Holy Spirit in the womb of the Virgin Mary, the Holy Spirit coming down upon her: and the power of the Most High overshadowing her; and so was made of a woman of the tribe of Judah, of the seed of Abraham and David according to the Scriptures; so that two whole, perfect, and distinct natures were inseparably joined together in one person, without conversion, composition, or confusion; which person is very God and very man, yet one Christ, the only mediator between God and man.
The blending of the two became ONE inseparable.
The nature of Christ is NOT like that of a salad in which the parts may be distinguished but like that of a cake in which the blending and forming make of the parts a single whole - inseparable without conversion, composition, or confusion. Christ had no "division of powers" within himself. He was ONE, and One with God, and is God.
There is no difference in what I have stated as my view, the Scriptures, the Nicene Creed, The Athanasian Creed, nor the London Confession of Faith 1689 edition.
