OURS IS AN age of interaction, mobility, and change. Unlike most of our grandparents, many of us have moved several times in our lifetimes and have seen our neighbors move in and out. We are more intensely aware, even in our own neighborhoods, that our kind of faith is not the only kind. We see how others have been shaped by very different histories than our own. It becomes clear to us that we, too, have been shaped—and continue to be shaped—by our own history.
Fuller Theological Seminary, where I teach, is in California. Every now and then we feel the ground shifting. The chandelier in our dining room swings or the bed on which we are lying begins to rock. The whole world may not be experiencing little earthquakes as we are, but people are surely experiencing change and variety in faiths and ideologies. This change and diversity can rock a person’s faith. We ask, How do we validate the truth of what we perceive and what we believe? In our time of pluralistic encounter with multiple ideologies and religions and with rapid social, economic, and political change, people search for what Dietrich Bonhoeffer called solid ground to stand on.
