Chuck Colson notes how several prominent atheists have changed their tunes:
Well-known scholar Antony Flew was the first, saying he had to go "where the evidence [led]." Evolutionary theory, he concluded, has no reasonable explanation for the origin of life. When I met with Flew in Oxford, he told me that while he had not come to believe in the biblical God, he had concluded that atheism is not logically sustainable.
More recently, A. N. Wilson, once thought to be the next C. S. Lewis who then renounced his faith and spent years mocking Christianity, returned to faith. The reason, he said in an interview with New Statesman, was that atheists "are missing out on some very basic experiences of life." Listening to Bach and reading the works of religious authors, he realized that their worldview or "perception of life was deeper, wiser, and more rounded than my own."He noticed that the people who insist we are "simply anthropoid apes" cannot account for things as basic as language, love, and music. That, along with the "even stronger argument" of how the "Christian faith transforms individual lives," convinced Wilson that "the religion of the incarnation … is simply true."
Likewise, Matthew Parris, another well-known British atheist, made the mistake of visiting Christian aid workers in Malawi, where he saw the power of the gospel transforming them and others. Concerned with what he saw, he wrote that it "confounds my ideological beliefs, stubbornly refuses to fit my worldview, and has embarrassed my growing belief that there is no God." While Parris is unwilling to follow where his observations lead, he is obviously wrestling with how Christianity makes better sense of the world than other worldviews.
