I have studied about the Bride of Christ. It appears that there was an undivided Kingdom under David and Solomon. Then after Solomon the kingdom divided, The House of Judah and The House of Israel. God ended up divorcing the House of Israel. They were first taken into captivity by Assyria in 721 BC and then later scattered throughout the earth. Because they never repented and returned to God, as the House of Judah did after their 70 years in Babylonian captivity, they multiplied and filled the earth and forgot where they came from and who their God was. Because God divorced The House of Israel for their adultress lifestyle, ie serving other gods, God stated in His own Law, Deut. 24:1-4, that He could never remarry them. The only recourse was for God to die, resurrect and then take them to be His Bride. Sound familiar? Jesus, who was The WORD come alive, willfully martyred Himself so that He could die and resurrect and marry those God had divorced. The Gentiles are mostly the lost sheep, the ten tribes of Israel, and Jesus has come to bring the Kingdom back to the undivided Kingdom. Most Christians don't read the stories in the Torah or the Prophets or the Writings (we call it the Old Testament) because they think it does not pertain to them.
Released from the Law
Rom 7:1 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?
Rom 7:2 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.
Rom 7:3 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.
Rom 7:4 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.
What LAW DO THEY KNOW?
Laws Concerning Divorce
Deu 24:1 When a man hath taken a wife, and married her, and it come to pass that she find no favour in his eyes, because he hath found some uncleanness in her: then let him write her a bill of divorcement, and give it in her hand, and send her out of his house.
Deu 24:2 And when she is departed out of his house, she may go and be another man's wife.
Deu 24:3 And if the latter husband hate her, and write her a bill of divorcement, and giveth it in her hand, and sendeth her out of his house; or if the latter husband die, which took her to be his wife;
Deu 24:4 Her former husband, which sent her away, may not take her again to be his wife, after that she is defiled; for that is abomination before the LORD: and thou shalt not cause the land to sin, which the LORD thy God giveth thee for an inheritance.
WAS JEREMIAH PERPLEXED HOW GOD COULD REMARRY THE HOUSE OF ISRAEL SINCE HIS OWN LAW FORBID TAKING HER BACK?
Jer 3:1 They say, If a man put away his wife, and she go from him, and become another man's, shall he return unto her again? shall not that land be greatly polluted? but thou hast played the harlot with many lovers; yet return again to me, saith the LORD.
Jesus came to be Immanuel "God with us" and he was sinless and He died so that the NEW COVENANT could be made with all the people and nations of the whole earth.
I believe we are to be adopted or grafted in to the Commonwealth of Israel. This is our calling, to lay down our lives with Christ and to raise up a new life, that has been washed and made ready for the Bridegroom for when He comes back from His Father's house to collect His Bride.
