I don't see any Biblical prohibition against tattoos in general. I don't have a tattoo, and don't plan on getting one, but I don't think it's necessarily a sin. Do you?
I don’t consider it a sin, I’m a Christian and have tattoos, I really don’t see the problem with them. Now I wouldn’t go get a tat of naked girl and profess to be a Christian, mine are music themed since I am a drummer and guitarist. It’s one of the ways I express my love of music and that’s all there is to it. One of mine is one of Stevie Ray Vaughan’s guitar “Lenny”. He is one of my favorite guitarists.
