From the King James Bible, our passage for today:
28 And God blessed them, and God said unto them, Be fruitful, and multiply, and replenish the earth, and subdue it: and have dominion over the fish of the sea, and over the fowl of the air, and over every living thing that moveth upon the earth.
From the New International Version Bible, our passage for today:
28 God blessed them and said to them, “Be fruitful and increase in number; fill the earth and subdue it. Rule over the fish in the sea and the birds in the sky and over every living creature that moves on the ground.”
To “reign over” something is to have absolute authority and control over it. God has ultimate rule over the earth, and he exercises his authority with loving care. When God delegated some of his authority to the human race, he expected us to take responsibility for the environment and the other creatures that share our planet. We must not be careless and wasteful as we fulfill his charge. God was careful in how he made this earth. We must not be careless in how we take care of it.
