Some people are kind, polite, and sweet-spirited until you try to get into their pews or their favorite church parking spot. Many folks want to serve God, but only as advisers. It is easier to preach ten sermons than it is to live one. We were called to be witnesses, not lawyers. When you get to your wit's end, you'll find God lives there.
People are funny.
They want the front of the bus, middle of the road, and the back of the church. Opportunity may knock once, but temptation bangs on your door for years. If the church wants a better pastor, it only needs to pray for the one it has. To make a long story short, don't tell it. I don't know why some people change churches.
