Yes I am sure about that
The Lord (Jesus) was betrothed to Israel when they came out of Egypt.
Jeremiah 2:2 RSV "Go and proclaim in the hearing of Jerusalem, Thus says the LORD, I remember the devotion of your youth, your love as a bride, how you followed me in the wilderness, in a land not sown.
The Lord gave Israel a bill of divorce
Jeremiah 3:1 RSV "If a man divorces his wife and she goes from him and becomes another man’s wife, will he return to her? Would not that land be greatly polluted? You have played the harlot with many lovers; and would you return to me? says the LORD.
Jeremiah 3:8 She saw that for all the adulteries of that faithless one, Israel, I had sent her away with a decree of divorce; yet her false sister Judah did not fear, but she too went and played the harlot.
The new covenant is the new marriage
Jeremiah 31:31-32 "Behold, the days are coming, says the LORD, when I will make a new covenant with the house of Israel and the house of Judah, 32 not like the covenant which I made with their fathers when I took them by the hand to bring them out of the land of Egypt, my covenant which they broke, though I was their husband, says the LORD.
The Lord cannot remarry unless Jesus or Israel died! Because Israel was scattered among the gentiles the only way for Jesus to marry all Israel is to marry the church which includes Israel scattered among the gentiles.
