What is the difference between lawful and unlawful use of the law?

The distinction between lawful and unlawful use of the law lies in the intent and understanding of the law's purpose. The lawful use, as explained in 1 Timothy 1:8, is to bring about an acknowledgment of our sinfulness and our need for salvation. It directs us to the grace found in Christ. Conversely, the unlawful use occurs when individuals attempt to justify themselves before God through their adherence to the law, as seen in the case of the Pharisee in Luke 18:9-14. This approach misapplies the law, leading to self-righteousness rather than repentance. The key takeaway is that the law should lead us to humility and dependence on Christ, not to self-sufficiency.
