In order to live to God I had to die to the law

The short version:

Gal 2:19-21
For I through the law died to the law that I might live to God. 20 I have been crucified with Christ; it is no longer I who live, but Christ lives in me; and the life which I now live in the flesh I live by faith in the Son of God, who loved me and gave Himself for me. 21 I do not set aside the grace of God; for if righteousness comes through the law, then Christ died in vain."


The extended version (Note: The following passage has nothing to do with any rules for Christian marriage. Paul was using the Jewish law pertaining to marriage to help his readers understand why those who were under the law could only be released from the law in one way - they had to die to it. If we try to be married to [joined with] both the Law and Christ, we are spiritual adulterers):

Rom 7:1-6
Do you not know, brothers - for I am speaking to men who know the law - that the law has authority over a man only as long as he lives? 2 For example, by law a married woman is bound to her husband as long as he is alive, but if her husband dies, she is released from the law of marriage. 3 So then, if she marries another man while her husband is still alive, she is called an adulteress. But if her husband dies, she is released from that law and is not an adulteress, even though she marries another man.

4 So, my brothers, you also died to the law through the body of Christ, that you might belong to another, to him who was raised from the dead, in order that we might bear fruit to God. 5 For when we were controlled by the sinful nature, the sinful passions aroused by the law were at work in our bodies, so that we bore fruit for death. 6 But now, by dying to what once bound us, we have been released from the law so that we serve in the new way of the Spirit, and not in the old way of the written code.

And a little more:

Col 2:13-14
And you, being dead in your trespasses and the uncircumcision of your flesh, He has made alive together with Him, having forgiven you all trespasses, 14 having wiped out the handwriting of requirements that was against us, which was contrary to us. And He has taken it out of the way, having nailed it to the cross.
