In answering the question of tattoos it's important to not only consider Leviticus 19:28 but also what Romans 14 teaches us about handling potentially contentious issues of conscience. On one side we have those who can not distinguish the difference between following their own conscience and requiring that everyone else does. On the other side we have some who recognize a liberty to get a tattoo while forgetting to partner this liberty with wisdom and love. Both of these errors causes division in the body of Christ. I'm hoping this video helps.
