A rebel who hates the law has a wrong relationship to the law. Naturally the law will bind him as a slave to serve sin. The legalist also has a wrong relationship to the law. The doctrine of salvation by means of sincere obedience to the law is the worst kind of antinomianism. The man who holds this doctrine is a debtor, and sin will get permission from the law to stir up all kinds of evil passions in him.
Justification means to be set right before the law.
And those who are set right before the law are not bound in prison. We do not have to serve it any more. We have no need to tremble at its power. Faith is not just a nod of assent. Unless it works, it is not faith at all but a counterfeit.
