What does 1 Timothy 1:9 mean?
In the prior verse, Paul mentioned those who use the Law incorrectly. He used a turn of phrase that these people use the Law "unlawfully." In other words, they miss the real purpose of the Law. This verse continues to clarify what Paul means. The Law, in truth, is meant to show man his sinfulness. Those who don't think they are sinners should check themselves against the Law. Those who know they are sinners need Christ, not legalism.Paul's reference to the Law here may refer specifically to when God gave Moses the Ten Commandments on Mount Sinai (Exodus 20). In fact, Paul's list of sins given here and in verse 10 mirror the pattern of the Ten Commandments. These are similar to lists Paul gave in other passages (1 Timothy 6:4–5; Romans 1:29–31; 1 Corinthians 5:10–11). All three descriptive pairs of people given in the first part of 1 Timothy 1:9 refer to the same group of people: those who disobey God's ways and live unholy lives. They correspond directly to the first three commandments.
The remainder of verses 9 and 10 include specific actions which break the Law. Attacking one's parents breaks the fifth of the Ten Commandments in Exodus 20:12. Murder violates the sixth commandment (Exodus 20:13).
