"God blessed them and said to them, 'Be fruitful and increase in number; fill the earth and subdue it. Rule over the fish of the sea and the birds of the air and over every living creature that moves on the ground.'" NIV translation
This verse not only reminds us that we were created to be rulers over the earth but it shows us the wisdom of God. You see, even before sin had entered the earth, God new that death was going to enter through sin. He gave us the order and ability to "replenish the earth" and therefore man still exists here today.
"Then God said, 'I give you every seed-bearing plant on the face of the whole earth and every tree that has fruit with seed in it. They will be yours for food.'" NIV translation
We see, here, that we all were created to be vegetarians. As we will see later on in our studies, blood contains life and we were not created to kill anything. We must remember that this is before the fall and so it is a perfect world without death.
"'And to all the beasts of the earth and all the birds of the air and all the creatures that move on the ground - everything that has the breath of life in it - I give every green plant for food.' And it was so." NIV translation
Not only were we, as humans, to be vegetarians but the animals of the earth were not meant to eat other animals. God did not want killing and death to be a part of the earth. It is going to be like this again during the millennial reign (Revelation 20) and on the new earth (Revelation 21).
"God saw all that he had made, and it was very good. And there was evening, and there was morning - the sixth day." NIV translation
At the close of the sixth day, everything had been created and put into perfect order. When God looked at the pieces of everything that He created on the first five days, He said that it was good. But, as we see here, when everything is done and put into His order we see that it was "very good". That is a reminder to us that we may have and do some "good" things but that is not what God wants for us. What God desires for each and every one of us is the "very good" which comes as His creation is in line with His will. We also see that the number six is associated with man or earthly completeness. Throughout the rest of the Bible, we will be reminded of this and it will help us to understand the things of God.
