It is not about anyone denying Jesus was manifested in the LIKENESS as a man.
It IS however, comprehending, that claiming Jesus "IS" a Human man, would be contending Jesus was created out of the dust of the earth and thus required to return to dust, WHICH IS a Specific teaching of Scripture that Applies to ALL (humans)...men OUT OF the earth.
Whereas scripture reveals Jesus came forth OUT from God.
Further, contending Jesus "IS" a HUMAN man, makes Him having been Manifested, the SAME "LIKENESS" as ALL Humans....and Scripture itself, LIMITED His "LIKENESS" to that of "FAITHFUL Jews".
God does NOT CHANGE.
God does NOT become the Created.
God CAN appear in A LIKENESS He chooses.
God Himself appeared in the Flesh "LIKENESS" of a FAITHFUL servant.
Eph 1
[9] Having made known unto us the mystery of his will, according to his good pleasure which he hath purposed in ......himself: !!
According TO:
Eph 1
5] Having predestinated us unto the adoption of children by Jesus Christ to himself, according to the good pleasure of his will...
Phil 2;
[5] Let this mind be in you, which was also in Christ Jesus:
[6] Who, being in the form of God, thought it not robbery to be equal with God:
[7] But made himself of no reputation, and took upon him the form of a servant, and was made in the likeness of men:
[8] And being found in fashion as a man, he humbled himself, and became obedient unto death, even the death of the cross.
Until you comprehend the difference between....IS HUMAN....and AS A MAN...
...our understanding will remain conflicted.
