I came to Christ only a couple of years ago, before that I was in the depths.
But for a while after coming to Christ I wore a wooden cross to represent His ressurrection, and as a witness to people. I figured if they saw the wooden cross, they'd know. String broke and I lost it, might make another one.
But right now I don't wear jewelry except my wedding ring. I figure whats the point if we're going to be "taken up" soon anyways.
