Hebrews / Question
Hebrews describes the Son as “the radiance of the glory of God” and “the exact imprint of his nature.” It also says he “upholds the universe by the word of his power” (Hebrews 1:3). This language explains why the Son’s status is greater than any created messenger.
Hebrews 1:3–4 continues describing God’s Son after Hebrews 1:1–2. The Son is portrayed as visibly expressing God’s glory and truly reflecting God’s own reality, while also sustaining everything by his powerful word. After making purification for sins “by himself,” he takes the honored seat at God’s right hand. These lines sit inside the book’s opening sweep (Hebrews 1:1–4), which moves from “God spoke long ago” to “God has spoken by a Son,” and then stacks claims about the Son’s role and rank.
Hebrews 1:3–4 presents the Son as uniquely tied to God’s own glory and reality, not merely as a messenger. The Son makes God visible (“radiance of his glory”) and truly represents what God is like (“very image of his substance”). These are explicit claims about who the Son is in relation to God.
