Some argue that the Messiah is the Eternal because if he is a man, he would have imperfect nature and can not save. This is a misleading concept because we cannot find anything in Scripture that leads us to this conclusion. Moreover, it is a contradiction because Yahweh cannot be sacrificed nor die. They use a verse in Isaiah to back their claim
Isaiah 9:2 The people who were walking in darkness have seen a great light; upon those who dwelt in the land of the shadow of death a light has shone.
We can find the same verse in Matthew
Matthew 4:16 the people who sat in darkness saw a great light, and upon those who sat in the land and shadow of death, light arose to them.
The proponents of this belief, based on these verses, argue that “the enemy tries to dissipate the Light (which is the understanding that the Father is the same as the Son) with darkness (believing they are different).
They use the ‘ad baculum’ fallacy which is to impose by force or fear: “A person that does not believe that the Messiah is the Eternal, is lost and goes to eternal hell.” They also argue that the love of the Eternal is just and that He would never create a man to be massacred for the forgiveness for the sins of others. Only the Eternal could pay humanity’s debt because it is eternal and not payable by a man.
They try to convince the believers that these ideas are extracted from Scripture.
We will see a few verses that will counter this belief
WHAT SCRIPTURE TEACHES
Numbers 23:19 El{God} is not a man, to lie; nor a son of man, to repent!
These words came from Balaam who was not an Yisra’elite but was inspired by the Eternal and on this occasion Yahweh was speaking through him. The great truth revealed in this verse is that Yahweh is not a man nor is He a son of man.
We see more in the book of Hebrews
Hebrews 2:17-18 17 Wherefore it was right, that he{Messiah} should in every manner resemble his brethren; that he might be merciful, and a high priest faithful in the things of Elohim, and might make reconciliation for the sins of the people. 18 For since He Himself has suffered, being tempted, He is able to help others who are tempted.
«faithful in the things of Elohim» – It is evident that there are two beings that are completely different here: Elohim and the High Priest
«being tempted» – Can Yahweh be tempted? Impossible.
James 1:13 [HRB] ...For Elohim is not tempted by evil
And if Yahweh cannot be tempted He cannot fail the test.(11:10)
