I think our friendship with God is symbiotic, though He does most of the giving!
Still a friendship spirituality is what we are offered, so we must bless Him also, maybe most by just constantly recognizing how Loving and cool amazing He is, and how much, for some reason, He digs us also, especially when we are being ourselves! Seeing spirituality as friendship was one of His themes in the book.
I don’t know if God “needs” us (that’s a deep theological question), but He certainly likes and loves us! And wants to be friends! That much I know. We’ve been friends as long as i can recall.
Entering as friends is the way and tone of Love. I try to practice that tone in my friendships on earth as well. Why not! If we are all eternal friends in the end, start practicing it here!
