We are no longer slaves to sin; a slave serves only his master; a slave to sin is his own law; But since God has written His law in people's hearts and consciences, people are not only slaves to sin, but because of their vision of the relationship they have with law, slaves of what they think and think they are doing . A slave to sin is a slave to the law. The law has only one purpose, and it is to show people their sin. That works with awareness to create pain. The law causes death. The power of the law only leads people to sin more. If a person is not delivered from sin, then he only knows the legal power of the law. In order that human beings by nature under the damning power of the law, and on the other hand under the power of their own law, since they do not keep the law of God, they excuse themselves from observing of the law. And live as if they weren't lawbreakers.So they go from one extreme to the other, and they are convicted, they apologize and thereby make one law for themselves and another law for everyone else, everyone is a terrible judge of the other.

But when we are in Christ we are no longer slaves to the law; but we can still make a law for ourselves, even if we have been freed from the law and become slaves of Christ, since the law with its power has been perfectly satisfied through Christ in his active and passive obedience, then we cannot have any measure of our fulfillment of the legal Requirements by living our Christian life through our own works. Since Christ's standard of law-abidingness is perfect, anything but that standard think we are more than we are, make ourselves a law, since we are still sinful and under the influence of the law, both physically and spiritually, then we cannot do them justice. 

If we think we can, then we are a law in ourselves. That is, we have separated ourselves from the head by experience, since we think that we can be justified by our own power.If we believe we have fulfilled the requirements of the law by being separated from its power to rule us, then we have not ceased to rely on our desire to make ourselves law; and we have returned to righteousness by the works of an unbeliever. That is why judgment begins in the house of God, that is, we are all silenced to keep our own law by seeing the only person who obeyed the law, the only real person.
