The popular Christian apologist Kreeft tackles many of the tough questions of our day concerning Christianity. In a series of imaginative "dialogues", Sal the Seeker and Chris the Christian deal with the profound mysteries of the Gospel. The result is a book that is both engaging and profound, a book that leads readers to initial faith—or to deeper faith.

"The stakes in these dialogues are high. Christianity is God's marriage proposal to the soul, says Kreeft, and the answer must be "yes" or "no". We can evade the claims of Jesus Christ for a while, but death brings evasion to an end. It is wiser to look at Christianity honestly now.

Yes or No? shows the truth of Jesus' promise that those who sincerely seek the truth shall find it. It is a road map for those who are honestly seeking the truth and a source of greater faith for those how have already found God. It presents the full challenge of the gospel in a way modern men and women can understand.
