The first (legal) tattoo I got was the writing on my wrist. I got it on my 18th birthday as a gift to myself and it was done by a friend of mine who is a tattoo artist. It reads "believe." Now, you might be thinking: weren't you an atheist when you were 18, Cassie? And my answer would be: yes, yes I was my friend.
When I got the tattoo, it had nothing to do with believing in the traditional religious sense. To me, it was a reminder to always believe in myself. Believe that I can do the hard things in life, believe that I can conquer whatever life throws at me. I got it on my right wrist as that is the hand that usually goes over your heart. It was personal; at least then.
Now, looking back on what I thought it meant at the time seems humorous. I think God was playing a prank on me (ha!). Never in my wildest dreams did I think that a tattoo I got as a reminder to believe in myself would become a reminder to believe in God. A reminder that God is in control; that I am little and He is SO big. A reminder that I CANNOT do the hard things in life alone; that I NEED him more than I need myself.
It's funny to look back on some of the things I did when I was atheist and realize that God even had a hand in things then. Even when I continued to deny Him with all of my being.
Has God ever played a "prank" on you that you only realized in hindsight?
