What does the Bible say about the lawful use of the law?

The Bible teaches that the law is good, just, and holy, embodying God's moral commandments. Its lawful use is to reveal our sinfulness and the holiness of God, acting as a mirror that shows us our need for salvation. When viewed rightly, the law brings forth the realization that we cannot fulfill it, thus pointing us to Christ as the only means of justification. As stated in Galatians 3:19-24, the law serves as a schoolmaster to guide us to Christ, reinforcing the idea that salvation comes through faith in Him alone, not through our adherence to the law.
