When God created Adam, He did more than simply place the first man in a garden—He entered into a covenant with him as the head of all humanity. As God's royal image-bearer, Adam was regarded as God's son and representative king, called to trust God's word, obey His commands, and extend His good rule so that the earth would be filled with the life-giving knowledge of God's glory. From the beginning, God purposed to advance His glorious kingdom through covenant.
