JI Packer tells a story that illustrates the difference between travelers, those that are on a journey, and observers, those that observe and take notice of travelers. Observers may talk about the journey the travelers are on, they may talk of what the road is like, and where the road is going, but unfortunately they are not on the road … they see it and know it exists in theory. Travelers, on the other hand, don’t simply talk about it, they are on it. They deal with challenges like “Which way do I go?” and “How can I possibly make it another step?” They approach these questions very differently than the observers. It is immensely practical to them. The issue of marriage and divorce, for anybody, is not totally theoretical; nevertheless, there are some who are more like travelers and others like observers when they approach this topic, and Jesus has much to say about it.
