### A pastor's wife was expecting...

A pastor's wife was expecting a baby, so he stood before the congregation and asked for a raise. After much discussion, they passed a rule that whenever the pastor's family expanded, so would his paycheck.
After 6 children, this started to get expensive and the congregation decided to hold another meeting to discuss the pastor's expanding salary.
A great deal of yelling and inner bickering ensued, as to how much the pastor's additional children were costing the church, and how much more it could potentially cost.
After listening to them for about an hour, the pastor rose from his chair and spoke, "Children are a gift from God, and we will take as many gifts as He gives us."
Silence fell over the congregation. In the back pew, a little old lady struggled to stand, and finally said in her frail voice,
"Rain is also a gift from God, but when we get too much of it, we wear rubbers."
The entire said, "Amen."
