John Stott is addressing an issue that was important maybe 50 years ago. And is still today. I found the first chapter or two a little dated, but the third and forth chapters in this very short book were pure gold. The importance of the mind, i.e. of understanding and reason, is explored in chapter three in the context of: Worship; Faith; Gospel; Holiness; Guidance; Evangelism; and Ministry.
In regard to reasoning and sharing the gospel, Stott writes, "All human beings think, because God made a human being a thinking creature. The teaching of Jesus himself, although beautifully simple, certainly made his listeners think." And "Our duty then is to avoid distorting or diluting the gospel, and at the same time to make it plain, to cut the word of truth straight so that people can follow it, lest 'when any one hears the word of the kingdom and does not understand it, the evil one comes and snatches away what is sown in his heart.' I fear that our clumsy explanations sometimes give the devil this very opportunity which he ought never to be allowed."
I believe, that many exvangelicals and others who have walked away from their faith, (some of whom I know), had clumsy, shallow explanations of the gospel; the origins and validity of the canon of scripture; the nature of the universe and its origin; and the nature of life, its origin and “evolution”. They were given simplistic answers, sometimes from people who valued blind faith and eschewed reason and intellectual rigor. How sad. That is not the approach of Jesus, or the apostles, including Paul. It is neither good stewardship of the gospel, or of the responsibility we have for evangelism and teaching truth.
This quote from J Gresham Meachen is priceless, "There must be the mysterious work of the Spirit of God in the new birth,” he wrote. “Without that, all our arguments are quite useless. But because argument is insufficient, it does not follow that it is unnecessary. What the Holy Spirit does in the new birth is not to make a man a Christian regardless of the evidence, but on the contrary to clear away the mists from his eyes and enable him to attend to the evidence."
And, I wholeheartedly join John Stott in the following prayer and thank God for people like Gavin Ortlund, Glen Schrivener, Frank Turek Wes Huff, John Lennox, and the late Tim Keller, who God has given us. "I pray earnestly that God will raise up today a new generation of Christian apologists or Christian communicators, who will combine an absolute loyalty to the biblical gospel and an unwavering confidence in the power of the Spirit with a deep and sensitive understanding of the contemporary alternatives to the gospel; who will relate the one to the other with freshness, pungency, authority and relevance; and who will use their minds to reach other minds for Christ."
