There is a story about a newly appointed preacher who preached a very fine sermon on his first Sunday in the church. The text was Matthew 26.24. No one can serve two masters; for a slave will either hate the one and love the other. You cannot serve God and Money. Everyone loved it. The next Sunday she preached the very same sermon. The people were perplexed but since it was a fine sermon no one spoke to him of the duplication. The next week he preached the sermon again. After the service the Chairpersons of the Personnel and Worship ministry teams came to the pastor and asked him why he was preaching the same sermon over and over again. The pastor said, "When we start doing what Jesus has invited us to do, I'll move on to something new!"
