Okay so why don't the Jews of modern Israel accept Yeshua as son of God?
They've been given the choice just as you have.
Because it wasnt mentioned anywhere in the OT that God would send his Son to earth. I don't care what the Gospels say in this issue but the Tanach doesn't say anything about the Trinity and doesn't say anything about a son.
Really, try again.
"I will declare the decree: the LORD hath said unto me, Thou art my Son; this day have I begotten thee." -- Psalm 2:7
"Kiss his son, or he will be angry and your way will lead to your destruction, for his wrath can flare up in a moment. Blessed are all who take refuge in him." -- Psalm 2:12
"Let us oppress the poor just man, and not spare the widow, nor honour the ancient grey hairs of the aged. But let our strength be the law of justice: for that which is feeble, is found to be nothing worth. Let us therefore lie in wait for the just, because he is not for our turn, and he is contrary to our doings, and upbraideth us with transgressions of the law, and divulgeth against us the sins of our way of life. He boasteth that he hath the knowledge of God, and calleth himself the son of God. He is become a censurer of our thoughts. He is grievous unto us, even to behold: for his life is not like other men's, and his ways are very different. We are esteemed by him as triflers, and he abstaineth from our ways as from filthiness, and he preferreth the latter end of the just, and glorieth that he hath God for his father. Let us see then if his words be true, and let us prove what shall happen to him, and we shall know what his end shall be. For if he be the true son of God, he will defend him, and will deliver him from the hands of his enemies. Let us examine him by outrages and tortures, that we may know his meekness and try his patience. Let us condemn him to a most shameful death: for there shall be respect had unto him by his words." Wisdom 2:10-20
"When your days are complete and you lie down with your fathers, I will raise up your descendant after you, who will come forth from you, and I will establish his kingdom. He shall build a house for My name, and I will establish the throne of his kingdom forever. I will be a father to him and he will be a son to Me; when he commits iniquity, I will correct him with the rod of men and the strokes of the sons of men, but My loving kindness shall not depart from him, as I took it away from Saul, whom I removed from before you. Your house and your kingdom shall endure before Me forever; your throne shall be established forever.” -- 2 Samuel 7:12-16
"Who has ascended into heaven and descended? Who has gathered the wind in His fists? Who has wrapped the waters in His garment? Who has established all the ends of the earth? What is His name or His son's name? Surely you know!" -- Proverbs 30:4
Isaiah 7:14 and Isaiah 9:6. Yeah I think there's enough mention in the Tanakh.
But that is not what Muslims believe.
No son of Israel would be saved except through him.
And yet there stood Moses and Elijah beside Yeshua on the mount. Huh, imagine that!
Yes my God, the Rabb of All creation who happens to be your LORD too
Oh, :nono: Yours is NOT the One True God of Israel. Islam spits on the gift of Grace of the One True God of Israel.
doesn't require a change in nationality of his believers.
Actually, His believers (believers in Yeshua) are adopted by God and so become His One eternal Nation.
He has send down prophets to all people from among them.
He didn't send Muhammad, dude! Muhammad contrived his god and chose himself as its prophet.
