20 And God said, Let the waters bring forth abundantly the moving creature that hath life, and fowl that may fly above the earth in the open firmament of heaven. 21 And God created great whales, and every living creature that moveth, which the waters brought forth abundantly, after their kind, and every winged fowl after his kind: and God saw that it was good. 22 And God blessed them, saying, Be fruitful, and multiply, and fill the waters in the seas, and let fowl multiply in the earth. 24 And God said, Let the earth bring forth the living creature after his kind, cattle, and creeping thing, and beast of the earth after his kind: and it was so.
There is an undeniable joyousness to God’s creation. “Bring forth abundantly,” “fowl that may fly above the earth,” “be fruitful, and multiply”…in these I hear a command to spread out, to explore, to uncover the beauty that God has hidden in nature.
Notice in these verses how God created the sea and populated it with vibrant life, the skies and populated it with vibrant life, the earth and populated it with vibrant life. He wanted every nook and cranny of His creation to be appreciated and adorned with life, and He instructed that life to propagate and fill the whole space around it.
After the fall animal life would become defined by a vicious struggle of life-and-death, a survival that was based on the termination of others. But as originally designed, life was meant to be a peaceful, joyful flourish.
