Hebrews 1:3
Who being the brightness of his glory, and the express image of his person, and upholding all things by the word of his power, when He had by himself purged our sins, sat down on the right hand of the Majesty on high:
Jesus is the brightnesss of God’s glory. Jesus is the express image of the Father. When you get to heaven, the one you see sitting on the throne is Jesus. He is the exact image of God.
Everything you see is held by the Word of God.
Jesus gave Himself as an offering for us to rid us from sin.
