A bit of AW Tozer
"The most effective argument for Christianity is still the good lives of those who profess it. A company of pure-living cheerful Christians in the community is stronger proof that Christ is risen than any learned treatise could ever be."
"When the Church in America rejected the example of good men and women and chose for her pattern the celebrity of the hour, she suffered the greater loss that she has since discovered. Human greatness cannot be determined by popularity polls and not by the number of lines any man rates in the public press."
The Christian who is zealous to promote the cause of Christ can begin by living in the power of the Spirit and so reproducing the life of Christ in the sight of men. The world may pretend not to see but it will see, nevertheless and more than likely it will get into serious trouble with its conscience over what it sees."
