Why is the transfiguration of Jesus important for Christians?

The transfiguration of Jesus, as detailed in Matthew 17:1-8, is significant because it provides a glimpse into the divine glory of Christ, affirming His identity as both God and man. This event showcases His dual nature and serves as a pivotal moment to strengthen the faith of His disciples, who witnessed His majestic transformation. Furthermore, it symbolizes the fulfillment of God's plan for redemption, solidifying Christ's role in salvation history. The transfiguration reassures believers of His ultimate authority and the hope of our own glorification as seen in 1 John 3:2, where it is promised that we shall be like Him when He appears.
