Tattoos are amoral. But, I like the body God gave me. I think he is the master designer and his creation (as marred and flawed by the fall that it may be) is perfect. That goes for all those who may read this. God made each one as a masterpiece and his handiwork doesn't need any improvement. In fact it is our eyes and our perceptions of what looks good and what doesn't look good that are in desperate need of alteration. God is a Picasso not a Rembrandt. Still, each one is free to do with the outward appearance of their body as they see fit.
President Clinton tells a story about his junior high science teacher. The man was rather homely in apperance. And yet, he gave President Clinton and his classmates some sound advice that President Clinton has not forgotten to this day. This not so good looking science teacher share with them that every morning when he looked in the mirror he would say to himself John you are one handsome devil. He said that because he wanted them to decide for themselves that their lives had value. Well, at least one ended up President of the United States even though he came from a broken home with no pedigree.
Tattoos are amoral; God gives freedom; but you are a masterpiece and once you add a tattoo God's masterpiece will be forever lessened from what it was meant to be - unique, one of a kind, incomparable.
