In discussing Scripture with people through the years, I have been asked why we don't believe in the Old Testament. And you know what? I'm not sure how to answer that. My 1st response is to say, "Sure, I beiieve in the Old Testament." But what they mean is why don't I follow it.
Well, on closer scrutiny -- they don't either. In my daily Bible readings, I have been plodding through Moses' expounding on the Law. The dietary laws, sexual laws, purification laws, etc. I am bothered that the homosexual community says, "We are not under the Law of Moses any more, so what he said about homosexuality does not apply." And while that bothers me, I would have no problem if someone wanted to cook a young goat in its mother's milk (Ex. 23: 19). And my favorite food is probably shrimp -- followed closely by catfish (both considered unclean in the Old Testament).
I realize that the New Testament reinforces many of the laws of the Old Testament -- such as the prohibition against homosexuality. And I know about Peter's vision of the clean and unclean foods, etc. I also know that Jesus said (Mt. 5: 17) that He did not come to abolish the Law, but to fulfill it. I know that, at least in part -- He accomplished that by being the perfect, one time sacrifice and also by fulfilling the Aaronic priesthood, etc And I also know that Paul said that Jesus nailed the Law to the cross.
But I still struggle with exactly how to make the transition and application. God is still the same God. His character has not changed. And lifestyles and attitudes that provoked Him to anger then must still do the same today.
I do know that I want to be about making Him smile.
