Sorry for prattling on, but it's hard to condense my thought down.
Are there some laws in Leviticus that are still applicable today? Yes. But NOT because they are "in the law". Laws pertaining to things like murder, sexual sins, coveting, immorality, justice, mercy, and others still carry weight.
Why?
Because LONG before there ever was a nation of Israel and LONG before the law was every born, murder was a sin and it still is. Adultery, lying, cruel treatment of others, homosexuality, and more were sins from the beginning and are still sins today. It was a sin when Cain killed Abel. It was a sin when Rueben has sex with his father's concubine. It was a sin when the residents of Sodom and Gomorrah participated in homosexuality. It was a sin when Abraham and Sarah lied to two different kings and led them to believe that they were not married. It was a sin when Joseph's brothers allowed their anger at their father to torment them to a hatred of their brother. All of this took place centuries BEFORE the law ever existed.
How could they be sins when there was no law?
Because of God's Holy Nature. We are to emulate Him. God does not murder, steal, lie, and covet. He cannot be cruel, unjust, unmerciful, or unloving. He will not turn his back on his people and seek out another people to love. Ergo, we are to be just like Him as close as we can.
The Holy standard of God's Nature runs like a golden thread from out of Himself into the universe before He said "let there be light", into the Creation, the Garden, and it threaded it's way OUT of the Garden, into the nation of Israel, the law, and it threaded it's way OUT of the law and INTO the New Testament and beyond and His Holy Standard still abides today.
We are to avoid sexual sins and sins of mistreating others and disrespecting God NOT because they are written down in the book of Leviticus, but because these sins represent what is opposed to the holy nature of God.
If we were to abstain from these sins BECAUSE they are written down in Leviticus, then we would have to participate in ALL of their lawful consequences. People today who committed adultery would have to be stoned in the streets. Young girls who become promiscuous would have to be burned at the stake. Young men who were rebellious would have to be publicly stoned. To adhere to the law for the law's sake, says Paul, is to adhere to ALL of it.
Now, does that mean that we can completely DISREGARD what Leviticus says?
Consider what Paul says in Galatians 5:1-4 and 13. [1] Christ has liberated us into freedom. Therefore stand firm and don't submit again to a yoke of slavery. [2] Take note! I, Paul, tell you that if you get circumcised, Christ will not benefit you at all. [3] Again I testify to every man who gets circumcised that he is obligated to keep the entire law. [4] You who are trying to be justified by the law are alienated from Christ; you have fallen from grace!..................... [13]For you are called to freedom, brothers; only don't use this freedom as an opportunity for the flesh, but serve one another through love. [14] For the entire law is fulfilled in one statement: You shall love your neighbor as yourself.
What does Christian liberty mean?
It means that there is nothing in the law that when violated is going to send you to hell on that account all by itself. Our personal and individual sins don't condemn us. Our sin nature condemns us. We aren't sinners because sin. We sin because we are sinners first - born with that nature. Like being born right-handed or left-handed. It means that one's righteousness is not connected with the law in any way, shape, or form.
It means that the civil and the ceremonial law found in Leviticus doesn't even apply to Christans. Period.
For example, it's not a sin to get a tattoo. It just isn't. But is it wise? Let's think. How many young men have professed their love for their girlfriends by getting their name tattooed on their necks. And then how many of those young men MARRIED someone else!! I know I would not enjoy being married to a wonderful Christian man with the name "CARMELITA" tattooed on his neck.
Drinking alcohol is not a sin. Drunkeness is most definitely a sin. Therefore, while we have the liberty to drink without condemnation, yet we know that drunkeness is a sin - extreme caution to point of abstaining for most people should be taken in this area.
Paul says very clearly that liberty is freedom from the chains of the law, but that a Christian should not just run "willy-nilly" off into "liberty land" and live for the flesh. He or she should instead, use that wonderful liberty in service to others.
For a Christian to think, "Well, the Bible says that the law has been annulled and I guess that means that I can do whatever I please" is a sign of a very weak-minded Christian.
A Christian should use his or her liberty, according to Paul, NOT to live in abandon, but to serve.
When in doubt about "do's" and "don't", we are to be imitators of Christ and God says that we are to be holy as He is holy. And Christ, Himself, said that the greatest two commandments were to love God and to love others as we love ourselves. If we get THOSE TWO commandments under our belt, we won't have to worry about anything else. <!-- / message --><!-- sig -->
