A book about great faith.

I was blessed to hear about this faith filled autobiography thanks to a transmission by godtv.
I had not heard about the tremendous work and faith of George Muller, a Believer in Christ Jesus, to whom he prayed for guidance and money at a time of great need for the orphans in the town of Bristol, England, in the 1800s.
I am not able to see how his way of raising money for missionary outreach, could be translated into our time as well, when many orphans, internationally and in Britain, need our help. It could happen, as with God all things are possible.
Being filled with the Holy Spirit, and living daily a life of devotion to God with consistent prayer, is the most brilliant, yet at times long suffering path of achieving true grace filled divine answers. God has all the best answers and by prayer, we can seek them.
