Whatever happened to "walking by FAITH, not by sight..."? That was the reason JWs wouldn't wear a cross (or, in their case, a "torture stake", ha) and why they looked down at people in Christendom for having a visible symbol of their faith.
Good point. I was thinking something similarly when I recall back in years past when I used to wear a cross and later a WWJD bracelet. To me, it was simply a symbol that I used to show the world who I identified as and the kind of life I was trying to lead. I would imagine JW’s that wear these logos do so for similar reasons.
