well, i am getting my nose pierced, and i mean, what harm will it do? you can take it out and it willl heal, it's not a permanent thing you can regret, and does God actually say in the bible not to pierce ourselves?
sure we are gods temple, and wearing jewelry in your nose isn't going to change that, and a piercing is just adding to our beautiful appearance, not transforming it. Does god knock down people with piercings? of course not, and i am sure if he didn't want us piercing our bodies he would convict us, ad so far he hasn't done that to me.
