I've always enjoyed that Gandhi quote, but I hadn't seen the other one. Thanks for sharing.I'm reminded of what you said after watching some Christians' antics as well, and I'm also reminded of these two quotes.
"I like your Christ, I do not like your Christians. Your Christians are so unlike your Christ." - Mahatma Gandhi
"The greatest single cause of atheism in the world today is Christians: who acknowledge Jesus with their lips, walk out the door, and deny Him by their lifestyle. That is what an unbelieving world simply finds unbelievable.” - Brennan Manning (also mentioned in the DC Talk song, "What if I Stumble?").
I'd often play this song by Casting Crowns when I was a Christian, and I recall how it made a few Christians around me feel very uncomfortable.
If only some people could see themselves looking from the outside.
