Psalm 36:6 places the preservation of man and beast in the same sentence: "O LORD, thou preservest man and beast." This is not an afterthought. The God who sustains human life sustains animal life with the same care. Proverbs 12:10 says a righteous man "regardeth the life of his animal" — the Hebrew rages is to know intimately, to attend to the inner life of. The person who loves an animal deeply is practicing the kind of attentiveness Proverbs describes as the mark of righteousness.
Revelation 5:13 describes every creature — in heaven, on earth, under the earth, in the sea — joining in the declaration of blessing and honor. The scope of creation's worship is wider than human participation. What that means for individual animals is not spelled out. But it suggests that the creation God made and called good is not simply consumed and forgotten by him.
