Nowhere is this more apparent than in the lives of some of his servants; Newton changed from slavetrader to abolitionist, R. A. Torrey, the great bible teacher was on the verge of suicide, the polished Earl of Shaftesbury became someone who changed the fortunes of the less well off. We shouldnt be surprised when we have the examples in the Bible of David and Paul of Tarsus John Pollocks deft biographical pen sweeps over great reformers, liberators and evangelists of the 18th & 19th centuries. He shows their spiritual development, often from unpromising beginnings, and encourages us to believe that God can use us too.
