Hydro Cannon, I'm looking for a job :[
As for the tattoos, I'm guessing you are talking about Leviticus 19:28 that says: "You shall not make gashes in your flesh for the dead, or incise any marks on yourselves: I am the Lord”
A lot of people like to justify that by explaining that we are no longer under the law of Moses or the Old Testament's laws - now we are under the laws of Christ as he set an example for us. And while I agree that is true, I think that Christians should look further before inking their bodies.
For example, if you look at the historical reason for the book of Leviticus, one of the main purposes of that particular verse and the ones surrounding it was to deal with the pagan rituals and religious beliefs. This law against piercings and cuttings was one of the laws against the pagan rituals.
Keep reading: it goes on to say in versed 26: "Do not eat meat that has not been drained of its blood," and verse 27, "Do not trim off the hair on your temples or trim your beards."
But we don't follow that anymore hahah. This was just a direct command to the Pagans to make them stop their senseless rituals. But we should still look to this historical text as an example. I personally don't think God wants us to walk around all tatted up if it does not do anything to glorify Him.
If anyone gets a tattoo, it should be a Christian symbol used to show their devotion. It can be used to open a story or start an example to use in ministry as I mentioned before. I actually dislike the idea of tattoos, but I think if I had 'serve' or לשרת on my wrist, not only can I share my ambitions to serve as Christ did, but I can remind myself daily when I see it that I need to devote my life as service to God.
