Gotta Serve Somebody
Paul doesn't give a picture of a master capturing a slave, but of the slave presenting themselves for work. To whom are we presenting ourselves to be owned by? There are only really two options: sin or obedience. The Christian is owned by obedience. We can't belong to both. Whose side we are on is seen in our actions. We are all guilty of sinning but if we are following Him we will not live in a lifestyle of sin. Our life is no longer about what we don't do, but our willing service to Him.
