I hear you.

You don't need to believe in a sky father to understand the need for good, and doing things with good intent. Honoring the spirit, rather than the letter of the law is the heart of Christian practice-- we call it being lead by the Holy Spirit, but anyone who acts with posterity in mind, who plants trees who's shade they will never enjoy, acts in accordance with the same good we worship. Being a good steward of this earth doesn't require religion. Any who act in the name of the future are my allies, even if they aren't co-religionists.
