Blessed to be a blessing?

A paraphrased story- Story courtesy of David Ravenhill's sermon, "The Cross"

A business man who was a multi-millionnaire liked to share his testimony with the church. It all began when he was a little boy, during the Great Depression, he only had 4 or 5 dollars. He went to a church where the missionary challenged the people to give. He put in 25 cents, but the missionary challenged the people to give more, telling them of the tremendous needs of the mission field. He dug into his pocket and took out another 25 cents, but the missionary kept pleading and didn't let up. Finally, the boy put in everything he had.

In conclusion, the business man said, this was why God had blessed his business today. God took that seed, and today I am a multi millionnaire.

After he shared his testimony, the church errupted into applause. After the cheers had died down, an old woman in the front row whispered softly, but loud enough for everyone to hear.
"I dare you to do it again".
