Final answer:
According to Paul's letter to the Galatians, God gave the Law to reveal sin and subsequently lead us to Christ, serving as a signal for the need for salvation beyond one's own ability to uphold the law.
Step-by-step explanation:
According to Paul's letter to the Galatians, God gave the Law to reveal sin and lead to Christ (option c). This purpose is emphasized in the New Testament where it is stated that the Law acted as a schoolmaster to bring us to Christ. In the broader context of Judeo-Christian tradition, the Law, which includes the 10 Commandments and the 613 laws and injunctions laid down by Moses, served to guide the moral and religious life of the Jewish people, setting boundaries and highlighting the need for a savior due to the human inability to fully keep the laws. This was evident in the strict religious customs, marriage laws, dietary restrictions, and moral commandments that the ancient Jewish people practiced to maintain their covenant with God and preserve their identity. Ultimately, the Law pointed to the insufficiency of human righteousness and the necessity for divine intervention and grace, symbolized through Christ according to Christian theology.
