In 2010 I published the article “Good Stuff!: The Material Creation and the Christian Faith,” Concordia Journal 36:3(2010): 245-262. It considered the role the material creation plays in the Christian faith and discussed this under the headings of creational, incarnational, sacramental and eschatological. I have explored this topic from a related perspective in the blog post "Why do they believe the sacraments are only symbols?: Presuppositions in reading Scripture."
I have put this material into a Bible study entitled "Good Stuff!: God's creation and the Christian faith" which I have used in my congregation, Good Shepherd Lutheran Church, Marion, IL. It was very well received and I want to make it available to anyone who may be interested in using it. It is available through the following link: Good Stuff Bible study.
The article and blog post should provide all of the background needed to teach it to a congregation.
