In Hebrews 1:1–4, the author declares that while God spoke through prophets in the past, He has now delivered His final and complete message through His Son, Jesus Christ. Jesus is revealed as the ultimate creator, sustainer, and heir of the universe, serving as the exact representation of God's being and the radiance of His glory. After achieving the purification of sins through His death, Jesus sat down at the right hand of God, claiming a supreme position that is far superior to any angelic being.
