I remember reading years ago of George Mueller, an incredible 19th Century man of faith who built five orphanages that housed 10,024 children during his lifetime. He built them on faith.
Once, three hundred of the orphans were dressed and ready for school, but there was no food in the orphanage for them to eat.
“Take the children to the dining room and set them at the tables,” he told the housemother. He then prayed, and thanked God for that which He provided, even before He had provided a bite to eat.
Within minutes a baker had knocked on the door and delivered bread to the children, telling Mueller that God had impressed it upon his heart to give it to the children. Then a milk man knocked on the door. His cart had broken down and the milk would spoil unless he found someone to use it. He gave the milk to the orphans.
Mueller never doubted that God would provide. Through his 92 years, Mueller lived by faith. In addition to five orphanages, he preached in the same church three times a week for most of sixty years. He worked beside D.L. Moody, Charles Spurgeon, and Hudson Taylor. He traveled to 42 nations, preaching the Gospel. In the end, he personally preached to over three million people. All the while, he trusted in God to pave the way and provide the means.
He took the promise of God to David and Solomon to heart. “Be strong and of good courage, and do it; do not fear nor be dismayed, for the Lord God—my God—will be with you. He will not leave you nor forsake you, until you have finished all the work for the service of the house of the Lord.”
Do not fear. The same God who called you to do His work, has already provided the means for you to complete that work.
