A great theologian notes there are two kinds of people in the world.
There are unbelievers who need to see they're under the dominion of sin. And there are believers who need to see they're no longer under the dominion of sin because they belong to Christ.
This is really astute, and points to the need for all to live in submission to Christ.
For He alone sets us free from sin's rule of deception so we can walk in the truth, love and beauty of His kingdom.
