I don't see any of that in the book of Galatians.The Old Testament is still our schoolmaster and there are laws in it that we still cannot break. What we are not under is the covenant, the Ten Commandments, nor all the ceremonial laws and feasts that Jesus fulfilled, but we still cannot marry our sister or brother, etc. And remarriage is another one that Jesus also. preached on. I obey them. My ex husband from 22 years ago is still the last man I kissed. He divorced me without cause, so I'm still married to him. I refuse to sin.
