God's original blessing was on humanity's dominion, a limited rulership, confined to the earth and its animal inhabitants. For that dominion, the blessing of God was upon multiplication and for increase. God's way is always increase. . . Everything created on earth was to reproduce and fill the void on the earth. Prosperity is not for selfish consumption but for the increase of God's dominion.
Health is always expansion.
Creation was formed with the wonder of self reproduction built into it by the most minuscule of seed. Now he who supplies seed to the sower and bread for food will also supply and increase your store of seed and will enlarge the harvest of your righteousness. And where His Word is breathed the seed will increase.
