How do we know that Jesus is the glory of the Lord?

According to the sermon, the glory of the Lord is revealed in the person and work of Jesus Christ. Isaiah 40 proclaims that the glory of the Lord shall be revealed, which the New Testament confirms, particularly in Hebrews 1 where Jesus is described as the brightness of His glory. Furthermore, in John 1:14, it is stated that the Word became flesh and dwelt among us, and we beheld His glory. This means that Jesus' life and mission encapsulate the divine glory, demonstrating God's nature through His actions and sacrifice.
