I do not like tattoos. Never got one & will never willingly get one. But just like so many things in this world today, it's become normal & accepted by society. When that happens, we have a generation that doesn't even think of the consequences of getting one (or 20). So, whaddaya do? If worship music hadn't changed, would we be drawing in teens? If the unspoken Sunday dress code hadn't changed, would we be drawing in less? It's true that God never changes, but WE do. And while I believe that God alone can draw tennis shoe-clad people & heavy metal-loving teens, I also believe that God didn't reiterate any laws against tattoos in the NT because He foresaw such a time as this.
I agree about not liking tattoos, and never willingly getting one. And frankly I can't see anyone, for any reason, forcing me to have one.
However, I disagree that the church needs to change to fit the times. It says in Jeremiah 2:11, "Hath a nation changed their gods, which are yet no gods? but my people have changed their glory for that which doth not profit." Why should Christians have to change the manner in which they worship in order to appeal to the world? The whole point is for us as Christians to be so different from the world that they cannot help noticing that we are not like them - and then, when they ask us why, we can point to JESUS.
Going back to the topic of tattoos, though. Would people approve of someone scribbling graffiti on the walls of a church, whatever message they might be putting up there? Before anyone asks what the one has to do with the other, they should remember that our bodies are the temple of the Holy Spirit (1 Corinthians 6:19). So, using that analogy, tattooing is like scribbling on the walls of God's temple.
Looking at it another way, even putting aside the right or wrong of tattooing itself, what about the matter of decency? There are some people who want tattoos on private parts of their bodies. Would it be right for a Christian woman - or man, for that matter - to see the nakedness of another? I think the Old Testament would have something to say about that.
