“Sin” is not just “doing things God has forbidden.” It is, as we saw, the failure to be fully functioning, God-reflecting human beings. That is what Paul sums up in 3:23: all sinned and fell short of God’s glory. He is referring to the glory that, as true humans, they should have possessed. This is the “glory” spoken of in Psalm 8: the status and responsibility of looking after God’s world on his behalf. This status and this activity are sustained by true worship of the true God. This is the royal vocation, undergirded by the priestly vocation.
