Not the discussion topic, but I wish to elaborate with scripture why Jesus had to die.
1) Jesus is Yah's salvation (Yeshua)
2) Jesus is Immanuel (God with us)
3) Jesus is the God of the OT, the one we call Yehovah YHWH=LORD
4) Yehovah divorced the House of Israel and His own laws forbid Him from taking them again. (Deuteronomy 24:1-4
5) Jeremiah was puzzled how the LORD could have them return unto Him. Jeremiah 3:1
6) Jesus said He has only come for the lost sheep of the House of Israel. Matthew 15:24
7) Apostle Paul figured out the Mystery of the Gospel. (Romans 7:1-4)
Rom 7:1-4 Know ye not, brethren, (for I speak to them that know the law,) how that the law hath dominion over a man as long as he liveth? 2 For the woman which hath an husband is bound by the law to her husband so long as he liveth; but if the husband be dead, she is loosed from the law of her husband. 3 So then if, while her husband liveth, she be married to another man, she shall be called an adulteress: but if her husband be dead, she is free from that law; so that she is no adulteress, though she be married to another man.
4 Wherefore, my brethren, ye also are become dead to the law by the body of Christ; that ye should be married to another, even to him who is raised from the dead, that we should bring forth fruit unto God.
8) Jeremiah 31:31 and Hebrews 8:8 both state the New Covenant is for the House of Israel and the House of Judah.
9) Paul teaches on being the wild olive tree being grafted into the Olive tree. The Olive tree is rooted in the Israelites and the commonwealth of Israel. (Romans 11:17-18)
10) Paul teaches on being adopted.
11) Paul teaches that Jesus is the promised heir to Isaac.
12) Fullness of the Gentiles is the Mystery of the Gospel, as Jacob/Israel pronounced Blessings on Joseph's two sons, that the younger should become a multitude of Nations. (See Romans 11:25 and Genesis 48:19).
13) Mat_24:14
And this gospel of the kingdom shall be preached in all the world for a witness unto all nations; and then shall the end come.
