INTEGRITY ON A BUS
One Sunday a pastor preached a sermon on honesty. Monday morning he took the bus took get to his office. He paid the fare, and the bus driver gave him back too much change. During the rest of the journey, the pastor was rationalizing how God had provided him with some extra money he needed for the week. But he just could not live with himself, so before he got off the bus, he proceeded to give back the extra money and said to the driver, "You have made a mistake. You've given me too much change."
The driver smiled and said, "There was no mistake. I was at your church yesterday and heard you preach on honesty. So I decided to put you to a test this morning."
We call that integrity. It's what God calls for in this 3rd commandment: "You shall not misuse the name of the Lord your God..."
