How do we know God's commands are still relevant for Christians today?

While the specific rituals and laws given in the Old Testament serve to set apart a covenant community, understanding these commands through the lens of the New Covenant reveals their ongoing relevance. Jesus Christ fulfilled the Law, and His teachings and the apostles' instructions guide believers in living by grace while still honoring the moral principles inherent in God's commands. The essence of obedience, grounded in love and faith, continues to motivate how Christians live today, reflecting the transformative power of the Holy Spirit in their lives.
