On one hand, we were created by God to enjoy his grace. Apart from everything else God created, we were made in his image. We alone have the capacity to enjoy God in intimate relationship with him. The first word the Bible uses to describe that relationship is blessing. God blessed the human race not because of any merit or inherent worth in in us, but simply out of pure, unadulterated grace. God created humankind to enjoy his grace.
But that was not the end of the story, because on the other hand, God immediately followed his blessing with a command. “God blessed them and said to them, ‘Be fruitful and increase in number; fill the earth and subdue it.’ ” God gave his people his image for a reason – so that they might multiply his image throughout the world. He created human beings, not only to enjoy his grace in relationship with him, but also to extend his glory to the ends of the earth.
Simple enough. Enjoy his grace and extend his glory. This is the twofold purpose behind the creation of the human race in Genesis 1, and it sets the stage for an entire Book that revolves around the same purpose. In every genre of biblical literature and every stage of biblical history, God is seen pouring out his grace on his people for the sake of his glory among all peoples.
