Os Guinness recognizes that shifting culture and changing times have left us with great opportunity to witness to the truth of the Christian faith.
However, Guinness also proposes that to take advantage of this opportunity, we must recover the art of Christian persuasion. Much more than a simple evangelistic method, persuasion puts heart and mind to the task of convincing others that the faith deserves a hearing.
Guinness writes in an entertaining, and quotable fashion. He says:
…many of us who take the good news of Jesus seriously are eager and ready to share the good news when we meet people who are open, interested or in need of what we have to share. But we are less effective when we encounter people who are not open, not interested or not needy — in other words, people who are closed, indifferent, hostile, skeptical, or apathetic, and therefore require persuasion.
But Guinness is convinced that not only is every believer an apologist, but can be persuasive.
