Like craftsmen working on a great cathedral, we have each been given instructions about the particular stone we are to spend our lives carving, without knowing or being able to guess where it will take its place within the grand design. We are assured, by the words of Paul and by Jesus’ resurrection as the launch of that new creation, that the work we do is not in vain. That says it all. That is the mandate we need for every act of justice and mercy, every program of ecology, every effort to reflect God’s wise stewardly image into his creation.
