 Paul asked in Galatians 3.19, What then was the purpose of the law? Well, it was added because of transgressions until the seed to whom the promise referred had come. In the following verses, Paul described the law as a schoolmaster or guardian that watched over the Jewish people until faith in Christ was to come. Verse 24 says, So the law was put in charge to lead us to Christ, that we might be justified by faith.
