As a child of God, do you ever consider yourself royalty? If so, does your behavior reflect that status?
What would your thoughts be if you were in a country led by a King/Queen and saw their children behaving like hoydens? What if you saw they were totally out of control? What would you think of that King?
What do others who HEAR you say you are a Christian, but find you doing the same actions as anyone else who does not follow/believe in God/Bible?
What would your behavior make them think of God? Remember, we may be the only sermon/Bible a neighbor ever reads. Is it a good one?
