God's signature is on the whole of nature. All creatures are love letters from God to us. They are outbursts of love. The whole of nature is bursting with love, set in it by God, who is love, to kindle the fire of love in us. All things have no other reason for existing, no other meaning. They can give us no satisfaction or pleasure beyond this, to stir in us the love of God.
— Ernesto Cardenal, Abide in Love
