No one ever says, “I have decided to forsake the glories of the kingdom of God to pursue the self-oriented glories of my own kingdom.” Instead, because of the blindness of sin and the fact that we exist in little moments , so much of our kingdom building takes place without conscious intentionality. And because we have defined biblical morality as the keeping of a set of rules , rather than the ownership of our hearts by the Lord, much of the conflict of kingdoms goes unnoticed. As a result, our lives end up being shaped by a confusing mix of big kingdom rules (the kingdom of God) and little kingdom rules (the kingdom of self).
