David Smithers, a prolific author on men and women of prayer, calls out for prayer that contains sacrifice. "Surround yourselves with courageous,daring--yes, even extreme--examples of faith," he exhorts, "and they will nurture in you an extreme Christianity." Smithers cites fervent intercessors whose prayer exemplified "the outermost edge", such as Jesus, Moses, Paul, David Brainerd, Daniel Nash and numerous others to "teach us to be violent in believing." NOTE: Extreme Prayer High Quality is the complete sermon which comprises "Extreme Prayer - Part 1" and "Extreme Prayer - Part 2".
