God and nature are inseparable in Psalms. We're talking peanut butter and jelly, popcorn and movies, Barry White and singing about love inseparable. God was originally considered a storm god, so it's no wonder he's in tune with nature.
What does God do with this connection? He puts on a show. If the Israelites needed an enemy destroyed, he would rain down a storm of fire and water. And it's a two-way street: God demanded sacrifices from nature in the form of animal offerings.
If God's domain was the sky, what do humans get? Well, according to Psalm 147, we get earth. Oh, and God.
