The Jewish people entered into a covenant with God at Mount Sinai, when they accepted God’s Law.

The Jewish people, as well as God, consider this covenant to be a marriage covenant. Throughout the Old Testament, from the time of the giving of the Law, God refers to Himself as Husband to the Jewish people.

Then, God spoke about making a new covenant. But what about their covenant at Sinai? How could they be released from this covenant to enter into a new covenant with God? (Jeremiah 31:31-34).

Apostle Paul explains to the Jewish people – them that know the Law - God’s plan. He explained how, according to the Law, God made a way of escape for them.

"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? [the law applies only while a person is living].

“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. [When a woman marries, the law binds her to her husband as long as he is alive. But if he dies, the laws of marriage no longer apply to her.]

“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." - Romans 7:1-3 KJV [So while her husband is alive, she would be committing adultery if she married another man. But if her husband dies, she is free from that law and does not commit adultery when she remarries.]

The way that God would release His people from their binding marriage covenant of the Law was to die.

But how could God die?? He is an eternal Spirit, He cannot die.

Yet, when God robed Himself in flesh and blood, born of a woman, His flesh was able to die. God released His people from their marriage covenant with the Law by His death, burial, and resurrection so that they could enter His new covenant of mercy. (1Timothy 3:16, Acts 20:28, Jeremiah 31:31-34).

Apostle Paul then explains what the Jewish people must do.  

Just as Christ died, was buried, and rose again, the Jewish people must die to sin, be buried with Jesus by water baptism in Jesus name, and rise to live a new holy life in His Spirit.

"Wherefore, my brethren, ye also are become dead to the law by the body of Christ [You died to the power of the law when you died with Christ.]; that ye should be married to another, even to him who is raised from the dead [and now you are united with the one who was raised from the dead], that we should bring forth fruit unto God." - Romans 7:4 KJV

The Jewish people are now free to enter the New Covenant of grace by marriage to their very own husband that has brought them grace, Jesus Christ - God manifest in the flesh - that rose from the dead. (John 1:17)

"For when we were in the flesh, the motions of sins, which were by the law, did work in our members to bring forth fruit unto death. [When we were controlled by our old nature, sinful desires were at work within us, and the law aroused these evil desires that produced a harvest of sinful deeds, resulting in death.]

“But now we are delivered from the law, that being dead wherein we were held; that we should serve in newness of spirit, and not in the oldness of the letter. [But now we have been released from the law, for we died to it and are no longer captive to its power. Now we can serve God, not in the old way of obeying the letter of the law, but in the new way of living in the Spirit.]" - Romans 7:5-6 KJV
