The beginning

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 birds of the heavens, and over every living thing that moveth upon the earth. - Gen 1:28 (ASV)

This seems to be more than a bare permission but a direction and an advice to man. Having dominion over Eden, on a smaller scale, Adam was going to be able to fill and subdue it. If he managed to be faithful and able with little, his territory was going to be expanded and so as his rulership. Mat 25:14

God does not give us more than what we can handle. Just enough that we can get used to the idea of more. One has to grow, increase capacity, enlarge his/her tents for more. If Adam was able to manage Eden, he was going to see his rulership, his Kingdom expanding around the whole earth. God qualifies us for promotion.

That is how the Kingdom moves. The Kingdom of God is in motion. He who rules his spirit is better than he who takes a city. See Prov 16:32. It starts with managing one's self. You have to start by managing the private facet of life before venturing much into the public one. Then God begins to give you cities, and Nations.

The Kingdom of God is within us. Luke 17:20-21. We therefore need to pread it buy proclaiming the Word of God. This is the time. The Kingdom of God is at hand. Then God will give us more.
