" I was reading the book of Leviticus and learned that one of its major themes is the importance of sustainably caring for the earth. That’s in the Bible? I then went back to the poem that begins the Bible in the book of Genesis. Yes. It’s there as well. This sacred responsibility to care for the earth. In the Bible, having a healthy and sustainable relationship with the earth is not a cause or political agenda, it’s an obvious and unavoidable fact about human life. Any healthy spiritual vision for life begins with the awareness that everything is connected to everything else, and that begins with us having a healthy connection with the earth. "
