In the creation story of the Bible, humans are charged with caring for the earth. That's our prime role, our work.
"Then the Lord God took the man and put him in the Garden of Eden to work it and take care of it." Genesis 2, v 15, New International Version
This is a powerful reminder of our connection with the earth, our responsibility to it and our indebtedness to it, as well. Regardless of whether you believe this story is literal or symbolic, or whether the Bible is a sacred text for you, I think the story is compelling.
I believe that protecting the earth is a spiritual calling, and that we are in a spiritual crisis.
Environmental issues need to be discussed in your church, temple, synagogue. In your Sunday tea (or coffee) with friends or in your tent in the forest. Be the initiator of change and discuss the care of the earth.
One of my favorite philosophical jokes is this: "If God looks at what we've done to the Earth, why would we be allowed into heaven?" It's a joke with serious contemplative opportunities!
Salvation may just mean we have to save the planet. Save the planet, save ourselves.
