Hebrews 1:3 says that Jesus, the Son of God, shows us exactly what God is like and holds the whole universe together by his powerful word. After he had cleansed people from their sins, he took his place of honor at God’s right hand. The verse is written by the unnamed author of the letter to the Hebrews, and it speaks about the Son as the one through whom God has now spoken to us.
His Son is the radiance of his glory, the very image of his substance, and upholding all things by the word of his power, who, when he had by himself purified us of our sins, sat down on the right hand of the Majesty on high…

What Hebrews 1:3 Means
The opening phrases use two images from light and from stamped metal. The Son is called the “radiance of his glory,” meaning the light that shines out from a bright source and reveals its brightness. He is also “the very image of his substance,” which means he is the exact imprint of who God really is. Anyone who wants to know what God is like can look at Jesus and see it clearly.
The verse then says the Son is “upholding all things by the word of his power.” The Son is not just a teacher who lived long ago. He actively sustains creation every moment, and he does it by a word of command that carries authority and strength. The sentence ends by describing his finished work: he cleansed us from sin and then sat down, a picture of a job completed and a position of authority restored.
What the verse does not do is explain every detail of how any of this works, or spell out how the cleansing is applied to each person. It sets out who Jesus is and what he has accomplished, and it leaves the reader to respond to that with trust.
The Context of Hebrews 1:3
The letter to the Hebrews was written to Christians, many of them probably of Jewish background, who were tempted to drift back toward old religious habits or to doubt that Jesus was greater than the angels, Moses, and the priests. The author opens with a strong claim: God once spoke through the prophets, but now he has spoken through his Son. Verse 3 is the first detailed description of who this Son is, and it prepares the reader for the argument that follows about Christ’s superiority.
The verses just after this one, in verses 4 through 6, show Jesus becoming “so much better than the angels” and quote Old Testament passages to make the point. Seeing verse 3 in this setting means reading it as the foundation for a larger case: if the Son is this glorious and this powerful, then nothing else in the old system can compare with him.

This verse says no one has ever seen God, but the one and only Son has made him known. It sets up the same idea as Hebrews 1:3 that Jesus is the way God becomes visible to us.
Colossians 1:15-17
15 Who is the image of the invisible God, the firstborn of all creation. 16 For by him all things were created, in the heavens and on the earth, things visible and things invisible, whether thrones or dominions or principalities or powers; all things have been created through him, and for him. 17 He is before all things, and in him all things are held together.

Paul describes Christ as the image of the invisible God and says all things were created through him and hold together in him. It expands the claim that the Son upholds all things.
A Short Prayer From Hebrews 1:3
Lord Jesus, you are the radiance of God’s glory and the exact picture of who the Father is. Thank you for showing us God clearly and for holding all things together by your powerful word. When I feel that my life is coming apart, help me remember that you are still upholding every part of it. Thank you that you have cleansed me from my sins and sat down in victory, so I can rest in what you have finished. Teach me to look at you and trust what I see. Amen.
