Until one comprehends the why & what, they have not the knowledge in their hearts of who, only their carnal premise of who He is.
The Scriptures say that both are blind in part, the house of Judah because they did not recognize the Messiah when He came, but that was also prophesied that it would happen well ahead of time. Then there is the out of Covenant house of Isra;el, who knowing of the prophesy of Messiah, but not understanding why He was to come. Thus the reason for all the divorce talk, the falling away, the grace that brings them back in.
But that's ok, I have brought forward the Word of YHVH and now it is up to HIM as to whom HE choose to see & hear it.
“why he came”
Matthew 1:21
she will bear a son and you shall call his name Jesus, for He will save His people from their sins.
if you don’t accept the NT, read Isaiah 53 to find out why he came.
