The law was given to address and manage human sinfulness, acting as a guide and a guardian until the arrival of Christ, who is referred to as the 'Seed' in this context. This highlights the temporary nature of the law, which was never intended to be the final solution for humanity's separation from God. Instead, it served to make people aware of their sins and their need for redemption. The law was delivered through angels and mediated, which signifies its divine origin and the seriousness with which it was given.
However, the law was not meant to replace the promise God made to Abraham, which was fulfilled in Christ. This promise was about faith and grace, offering a deeper and more complete relationship with God. The coming of Christ fulfilled this promise, providing a way for people to be justified by faith rather than by adherence to the law. This transition from law to grace is central to understanding the Christian faith, emphasizing that while the law had its purpose, it is through Christ that believers find true freedom and salvation.
