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

In the New Testament, particularly in the Gospel of John, Jesus directly points to His oneness with the Father, asserting, 'If you have seen me, you have seen the Father' (John 14:9). This highlights that Jesus embodies the glory of God as He reveals His love, grace, and truth. Furthermore, the New Testament emphasizes that the glory of God is ultimately displayed through Jesus' atoning work on the cross. Hebrews 1:3 tells us that Jesus is 'the radiance of the glory of God,' affirming that His life and sacrifice exemplify God's character and fulfill His redemptive plan for humanity.
