I am a Follower of Christ first and for most. I associate with outer like minded believers that feel the Southern Baptist more closely believe as Jesus taught. But that does not mean only Southern Baptist are the only ones going to heaven, by no means.
I believe my body is the Lords. For me tattoos are a sin. I believe that is what is best for Christians. Tattoos often stand for a rebellious spirit, and before one comes to Christ what a person has done with or to their body is covered in His blood. That is also true for us after we are saved too, all sin is covered by His blood if we confess our sins and repent.
Some Christians see this very differently. For me it is mainly about my body belongs to the Lord, and I want to be Holy before Him. I believe Gods WORD teaches us what is best for us even if it's in the Old testament. I am bound by the the teaching of Jesus Christ to obey His commands. Love totally for LORD and for others. I believe we are to obey the Commandments outlined in Exodus 20. I think Tattoos are best avoided, and to mark up ones body with anything but something that brings Glory to our LORD is most likely a sin, in my opinion.
