I've seen this before

"Going to church doesn't make you a christian any more
than standing in a garage makes you a car."

I've seen this post a few places now and i don't disagree with this, but I think a few things could be added.
Like;
You're more likely to be a Christian if you go to church but you'll never become a car standing in a garage.

What makes you a Christian?
Did a Christian quote this or a non-Christian?

As Christians and non Christians, it should be evidence to all that, those who know Christ will carry the same love of Jesus the living water.
The love He puts in you will pour out onto others. This will be the evidence of those who follow Christ.
