I have a Celtic Trinity knot on my calf, then on my other ankle an autism puzzle piece one. Then "Veritas" (Truth) is on the side of my left foot. I had a friend who did them. I've done two myself; one on another guy, then for fun one day I did a "pi" symbol on my leg
Wasn't hard at all; same as drawing with an ink pen to me once you print out the design on that special paper that leaves the outline.
I know I'm set free from the law but at the same time I love the law and delight in it (Psalms) so much of the Law I think is good for us. As for tattoos I don't see that as defacing God's Temple as long as it goes to God's glory as everything we do should be; eat, sleep, breath, talk; anything to His Glory. So for me it's more about what your tattoo is standing for and would God be pleased with it. The Trinity one and Veritas were done in that right thinking I believe. The Autism one was to remind me of helping others with Autism since I have a higher functioning version of it and I believe God wants me to minister to Christians with Autism since I've found such little help online when I first realized that was why my life was so different and lonely; feeling like I'm not living like I should according to His Word but I look at the prophets (not that I'm like that), and how they were different so not everyone is the same "ideal/perfect" Christian.
Oh and I'm sure it's already been mentioned, but Christian type tattoos can open up Christian discussions. And when I was struggling, I met with a young pastor around 26 who was just starting to preach and He has a lot of verses tattooed and it helped me feel like he wasn't going to judge me. God works in mysterious ways and opens doors where we don't expect all the time. So they can be an evangelical tool imho.
I kid
but they might of thought different if someone put graffiti up on the OT Temples!
(sorry for the long typing, it's something I'm trying to work on, I'm also bi-polar and my meds haven't been working the past month and I'm really a mess and have no idea what to do but keep sermons playing and reading devotionals. I've never been this bad in my mind before. Scripture comforts me and I get very emotional; then it goes away and I will feel very irritated and upset and I don't know why.
