The dominion mandate is not primarily agricultural or technological, but ethical, i.e. , it calls men to exercise dominion in the earth according to God's law-word for the honor and glory of God. Unregenerate man does not carry out any of his activities out of a love for God, and most often not out of a true love for his neighbor either. It is true that unregenerate man still retains to a degree the image of God, and, by nature, an impulse for dominion. But his reference is purely technological out of a motive for his own power and glory. However, the dominion mandate as originally given can be addressed only to righteous men, and that is why it is never given to unregenerate men in the Bible and is ultimately transferred to Jesus Christ.
Evangelism is absolutely necessary to the dominion mandate in the post-Fall world.
In fact, the Great Commission and the dominion mandate are closely related. For the record, so that it cannot be said that Einwechter does not practice what he preaches, my wife Linda and I have nine children. God's promise of fruitfulness to his people is a general promise that applies in most instances. Nevertheless, for his own purposes that often remain hidden from us, God sometimes withholds fruitfulness from faithful covenant-keeping men and women.
