 Because as believers, we don't need to follow the letter of the law, but we follow the spirit of the law. So the commandment to not sow mixed seed in a field or to wear mixed trousers with linen and say, well, God says you can't do that. Well, we could look at that and go, let's keep that. Or we could say, what was the purpose of this commandment? And so because some of them aren't commandments, they're instructions and some of them are precepts.
