I have always found the story of the brother Jared to be very interesting. I think it was fascinating that he took matters into his own hands and had the faith to go before the Lord to present his plan for light. I found a quote from President Harold B. Lee that was very meaningful. I think it balances the idea of faith and using your own mind to get things done.
"This is the principle in action. If you want the blessing, don't just kneel down and pray about it. Prepare yourselves in every conceivable way you can in order to make yourselves worthy to receive the blessing you seek." -President Harold B. Lee.
