??? Never said the Bible condoned it - just that it didn't call it a sin to have sex when not married.
Where does it say virginity is "God's law? Jesus told us that there were really two great commandments and that the love included in each meant no harm which fulfilled the intent of the Law - much of which was negated with the New Covenant, hence the folks who decided they would continue to follow the Law being rebuked for having fallen from Grace. (Not saying we shouldn't be better but that God, who made us, knew we couldn't be and decided to fulfill His Law for us by allowing His Son to be sacrificed).
The OT tells us what sexual immorality consists of. Here are the parts having to do with one's virginity: Exodus 22:16 “If a man seduces a virgin who is not betrothed and lies with her, he shall give the bride-price for her and make her his wife.
Leviticus 21:14 A widow, or a divorced woman, or a woman who has been defiled, or a prostitute, these he shall not marry. But he shall take as his wife a virgin of his own people,
Deuteronomy 22:19 and they shall fine him a hundred shekels of silver and give them to the father of the young woman, because he has brought a bad name upon a virgin of Israel. And she shall be his wife. He may not divorce her all his days.
Deuteronomy 22:20 But if the thing is true, that evidence of virginity was not found in the young woman, 21 then they shall bring out the young woman to the door of her father's house, and the men of her city shall stone her to death with stones, because she has done an outrageous thing in Israel by whoring in her father's house. So you shall purge the evil from your midst.
Jesus told us that there were really two great commandments and that the love included in each meant no harm which fulfilled the intent of the Law - much of which was negated with the New Covenant,
Nothing has been negated by the "New Covenant." To love God with all your heart is to keep His laws. ALL of them. The NT is very specific in calling out sinners on their sexual immorality. To say those OT laws no longer apply is leading people down the path of condemnation.
