'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.'
-Genesis 1:28 KJV
God instructed Adam to have dominion. Dominion for the Christian is when God has COMPLETE control of your life. If He does not have your life, how could you walk in the spirit of dominion?
Dominion brings light, empowerment, and development.
