There was a lady who lived next door to an atheist. Everyday, when the lady prayed, the atheist could hear her. He thought to himself, "she sure is crazy, praying all the time like that. Doesn't she know there isn't a God?". Many times while she was praying, he would go to her house and harass her, saying: "Lady, why do you pray all the time? Don't you know there is no God?". But she kept on praying.
One day, she ran out of groceries. As usual, she was praying, explaining her situation to God and thanking Him for what He was going to do. As usual, the atheist heard her praying and thought to himself, "Hmph!, I'll show her." He went to the store, bought a whole bunch of groceries, dropped them off on her front porch, rang the doorbell and hid in the bushes to see what she would do When she opened the door and saw the groceries, she began to praise the Lord with all her heart, ecstatic. The atheist then came out and said: " God didn't buy you those groceries, I did !". On hearing this, she started running down the street, shouting and praising the Lord.
When he finally caught up with her, he asked why she was doing that. She said: " I knew the Lord would provide me with groceries, but I didn't know he was going to make the devil pay for them !"
