What in the world is causing people to cut and mark their skin? SATAN? It sure is not the wish of a Holy God to do so. The BIBLE says NOT to cut and mark your skin. See Leviticus 19:28, King James Version, it reads, "Ye shall not make any cuttings in your flesh for the dead, nor print any marks upon you: I am the Lord."
It is one of the personal laws God wants you to follow.
Parents need to inform their children, early, before one becomes an adult. Just look at the Tattoos on on ball players covering entire arms. What a poor example they set as leaders to have people follow. This marking is there all the rest of your life. It is nothing to be proud of in latter years when you realize what you have done. Don't do it. God is looking out for your best interests, when God tells you NOT to do it.
