In the New Testament we are freed from all the old laws. Jesus for example cancelled the rules about kosher food (Mark 7:19; Acts 10:13-15). See the article "Astonishing Freedom." (Webmaster link please )
Some of the Old Testament laws have practical and health values. And
there are still wrath consequences for such activities as porneia
(sleeping around) and drunkenness. This means God trusts his children to use
their common sense. There are good practical reasons for not marking oneself
permanently with a tattoo, and those who do this will suffer regrets in this
life. But it is not (as used to be preached) a sin that sends us to hell.
