Does anyone believe that it is we sinful mortals who create and/or give life to children? It is God alone who bestows life! All we can do is prevent life and kill. Contrary to our inflated egos, we cannnot create (bara' - ברא ) anything nor give life to anything. God simply uses us as his tools.

Consider Luther's Words:
"This passage [Genesis 9:1], moreover, leads us to believe that children are a gift of God and come solely through the blessing of God, just as Ps. 127:3 shows. The heathen, who have not been instructed by the Word of God, believe that the propagation of the human race happens partly by nature, partly by accident, especially since those who are regarded as most suited for procreation often fail to have children. Therefore the heathen do not thank God for this gift, nor do they receive their children as the gift of God."
