These are some collected, unorganized thoughts on a good part of life: Dominion.
And God said, Let us make man in our image, after our likeness: and let them have dominion over the fish of the sea, and over the fowl of the air, and over the cattle, and over all the earth, and over every creeping thing that creepeth upon the earth.
Man is a rational animal. His role is dominion. No beast of the earth, whale, dinosaur, or worm is higher or more loved by God. Thus, mastery of this world is good.
All men despise the weak man, the coward. This is because the weak man fails in his first earthly role. It is good to be strong, that we might have dominion over the earth.
Dominion is not destruction. A good father has dominion over his family, but it is only the worst fathers that destroy their families. Man has authority on earth, and with authority comes responsibility. Thus dominion contains within it the idea of stewardship.
Contained within the idea of earthly dominion over the creatures of the earth and the earth herself is the idea that everything has a place, and a purpose. To master this earth is to fill our role, to take our rightful place. Woe to those who rebel against the role God has given.
Knowledge is power. Power is the ability to dominate. Thus the root of Dominion is Knowledge. This is nowhere more clearly illustrated than in the wondrous technology of our modern age. We can dominate the skies themselves, flying on mechanical wings, because of our knowledge. Thus, from the first command to dominion results the implied command to wisdom and understanding. Since wisdom and understanding come from God, who is Truth Itself, it is clear that the command to Dominion rightly understood is a command to know and love God.
Dominion is good, but God is Goodness Itself.
