Please understand that we believers in this age are under the Law of Christ, of the Spirit, of liberty, and of faith. That doesn't mean anything goes, but that we're led by the Spirit who gives us life. He doesn't lead us back to the Old Covenant, but to keep the spirit of the law, which is love. I've written extensively on this topic before. You can easily find the articles when you click on the "free pdf download" link or on the label "messages."
