What does Hebrews 1:3 mean by 'upholding all things'?

It means the Son is actively holding the universe in existence right now — not that he wound it up and stepped back, but that he is the ongoing reason everything continues to be.

"Who, being the radiance of his glory and the exact imprint of his nature, upholding all things by the word of his power." — Hebrews 1:3

The key word is pherōn (φέρων, G5342) — a present active participle, which in Greek signals continuous, ongoing action. It doesn't say the Son "upheld" things at creation and completed that task. It says he is upholding, right now, in the present tense. And the direct object is ta panta — literally "the all things," meaning the totality, with no exceptions.

What does that actually mean? Not that God is identical with the universe (pantheism), but that the universe depends on him in every moment. Think of it like a note held on an instrument: the note doesn't persist by inertia after the player stops — it only exists while the player sustains it. The writer of Hebrews is saying the universe is like that note, and Christ is like that player. Remove him and the note doesn't fade — it was never there.

Paul says the same thing from a slightly different angle: "In him all things hold together" (Col 1:17). The Greek verb there — synestēken (συνέστηκεν, G4921) — is a perfect tense, meaning "they were brought together and are still held together." And in Acts 17:28, Paul tells the philosophers of Athens: "In him we live and move and have our being." The middle form of "we are moved" (kinoumetha, G2795) is passive — we are not self-movers; we are being moved.

The tense structure within Hebrews 1:3 itself makes the point neatly. The verse contains three verbal ideas: the Son made purification (completed — aorist), he sat down at the right hand (completed — aorist), and he is upholding all things (ongoing — present participle). The redemptive work is finished. The cosmic sustaining is not, because it is not the kind of work that finishes.

This isn't decorative religious language. It's a direct claim about who holds the world together — and the grammar insists it is happening at this moment.
