a much shorter rant

So what does a Christian do when he or she sins and is caught by an unbeliever?

Um...admit it. Say you're wrong. This should be easy. But we get so afraid that we'll be exposed as being actual, real sinners, we normally respond with something like, "Christians aren't perfect, just forgiven." Or, "At least it's not as bad as..." Or flat out denial. Anything to take the attention off the sin.

Christians, people will be shocked if you're caught in a sin and respond in humility. Don't defend yourself. Don't make any excuses. Just humbly admit it and apologize. That's the Christian way to respond.
