Titus 3:9-15
9 “But avoid foolish controversies and genealogies and strife and disputes about the Law, for they are useless and worthless. 10 Reject a divisive person after a first and second warning, 11 knowing that such a person has deviated from what is right and is sinning, being self-condemned.12 When I send Artemas or Tychicus to you, make every effort to come to me at Nicopolis, for I have decided to spend the winter there.13 Diligently help Zenas the lawyer and Apollos on their way so that nothing is lacking for them. 14 Our people must also learn to engage in good deeds to meet pressing needs, so that they will not be unproductive.15 All who are with me greet you. Greet those who love us in the faith. Grace be with you all.”
Useless and worthless: Paul is blatant in his insistence that disputes about the law are worthless. This is because of Paul’s overall perspective on the differences between the Old Covenant and New Covenant but also because he was writing to Greeks, non-Jews, who never had the law. Therefore, arguing about the law was pointless for them. These arguments were also pointless because all who believe in Jesus are participating in a New Covenant, not the Old Covenant. Such admonition would be encouraging for the Greek believers as they combatted the false teachers who were mixing law and Gospel.
Self-condemned: Notice that Paul believed the false teachers to be condemned, not by God, but buy their own performance under the law. The law condemns all people because it can be kept by nobody. God, however, is not condemning. He wants to save all people through Christ.
Unproductive: For the Christian productiveness is fun because it arises out of our new natures. We do not produce good works in order to maintain or earn the righteousness which only comes from the regeneration of God.
