Why is understanding Jesus' authority important?

Jesus' authority is central to Christian faith as it establishes Him as the only means of salvation. In the Transfiguration account, the voice from heaven affirms Jesus as God's beloved Son, reinforcing His unique position and authority. This recognition is vital for believers, as it aligns with the broader theological narrative that Jesus fulfills both the Law and the Prophets, seen in His conversations with Moses and Elijah. The authority of Christ not only provides believers with the assurance of His redemptive work but also calls them to obedience and faith in the truths He reveals.
