Continued Prayer & Concern Causes Conversion

George Mueller said that, in 1844, five individuals were laid on his heart. He began to pray for them. Eighteen months passed away before one of them was converted. He prayed on for five years more, and another was converted. At the end of twelve-and-a-half years, a third was converted. Forty years later he was still praying for the other two, without missing one single day on any account whatever. But they were not yet converted. He felt encouraged, however, to continue in prayer. He was sure of receiving an answer in relation to the two who were still resisting the Spirit. (Acts and Facts).
