We have a God who can speak worlds into existence out of nothing at all (Genesis 1:1); it is no wonder He can do great things with so little to work with. He does not need or want the best or the brightest or those with tremendous talent (I Corinthians 1:26-31).
God wants ordinary people (like you and I) to step out with extraordinary faith and do amazing things. The Bible is full of examples of ordinary people exercising amazing faith in terrible times. It is easier to be faithful in the good times, but history is made when ordinary people are faithful in the worst of times.
