"Jesus, through the power of His sacrificial death and resurrection, frees sinners from the bondage of sin. By the power of the Holy Spirit through the Gospel, we are set free. Though while we are still in the flesh we may still struggle with sin, we are free from sin's dominion. To the extent we are in Christ, through faith, we no longer even need the external Law to keep us in line. We voluntarily -- freely -- do God's will, not out of compulsion or threats, but because we really want to please Him, and, because we are in God's love, we really do love our neighbors."
"People who are slaves of sin require laws, authorities, police officers, and government control to prevent them from harming other people. But people who have been freed from sin do not need external controls on their behavior. They internalize the moral law. They voluntarily -- of their own free will -- do what they should. They govern themselves, freely directing their own behavior; therefore, they are capable of governing themselves in a free political order.
"That free political order is not just for Christians, of course, and others who can, by whatever external means, govern their desires can also enjoy its liberties. But laws -- and prisons -- will still be necessary for those who refuse to govern themselves. Meanwhile, those who wish to preserve their freedom must be on guard against both tyrants and their own sin."
