…if you get a lot of religious mail don’t be mean to your mailman. He will notice the discrepancy (this after yet another nasty experience with an apparently devout believer).
And if you have religious bumper stickers do not be an aggressive and rude driver.
Also: if you are going to pray in public before a restaurant meal, make sure you are kind to your server, not demanding. And leave a generous tip. I don’t know how many times I have heard from waiters and waitresses – themselves believers – that if they see a prayer meeting before a meal they know they are probably going to get a crappy tip. I have even heard of people leaving a religious tract instead of a tip! Sheesh; what are those people thinking?
If you are going to appear in public as a Christian you have made yourself a representative of Christ.
For God’s sake, act like it.
