In biblical terms, it is wisdom we need to live together in the world. Wisdom is not gained by knowing what is right. Wisdom is gained by practicing what is right, and noticing what happens when that practice succeeds and when it fails. Wise people do not have to be certain what they believe before they act. They are free to act, trusting that the practice itself will teach them what they need to know. If you are not sure what to think about washing feet, for instance, then the best way to find out is to practice washing a pair or two. If you are not sure what to believe about your neighbour’s faith, then the best way to find out is to practice eating supper together. Reason can only work with the experience available to it. Wisdom atrophies if it is not walked on a regular basis.
