How do we know Jesus is the revelation of God?

Hebrews 1:1-3 underscores that God has spoken to us through His Son, Jesus Christ, who is the exact representation of His being. The sermon highlights that all the treasures of wisdom and knowledge are hidden in Christ, affirming that understanding God comes exclusively through knowing Jesus. As Isaiah experienced God's glory, he pointed to the fulfillment found in Christ. The divine revelation resides solely in Him, showing that through Jesus, humanity receives the clearest understanding of God's nature and will.
