What does it mean that God is a consuming fire?
The phrase comes at the very end of a passage in Hebrews that contrasts two mountains — Sinai, which burned with fire, and Zion, the place of grace. After all that grace, the writer closes with fire, and that raises the question: does the God who saves in kindness still burn?
Fire as the settled answer to evil
Throughout Scripture fire is the picture of God dealing with what cannot stand before Him. One writer notes that this is not a mood God happens to be in, but something that follows from what He is.
Samuel RidoutFire is the constant emblem of wrath and judgment, not of an arbitrary character, but that which is necessary and essential... Fire speaks of intense energy, of which God is the only source. As fire, it must burn up all that does not abide its test. So God must consume in judgment all that is opposed to His righteous and perfect will.
Whose God?
The wording matters. Hebrews does not say "the God of Israel was a consuming fire." It says our God — and the passage then draws a practical conclusion about how we serve.
Edward DennettIn Hebrews the apostle says that "our God is a consuming fire." It is to be carefully noticed that he speaks of "our" God, the God of Christians... he goes on, "Therefore let us be grateful for receiving a kingdom that cannot be shaken, and thus let us offer to God acceptable worship, with reverence and awe," and this because the God whom we serve is a "consuming fire." So once again the "consuming fire" is an expression of the holiness of God — in testing all our service, and in the necessary judgment of all that is evil in it.
Grace does not lower the standard. It is the same God who once spoke from the burning mountain.
J Wilson SmithGod in grace, though He bears with the sinner and with an unfaithful Church, is as intolerant of evil as God presented in the law. He is the same God in His essential hatred of sin at all times, and so the exhortation fits perfectly: "let us offer to God acceptable worship, with reverence and awe."
Not a God behind Christ
The verse is often read as describing some other, harsher God standing behind the God of the gospel. One writer rejects that reading outright.
J. N. DarbyIt is written, "our God is a consuming fire." This expression is sometimes wrongly interpreted, as if it were spoken of God out of Christ. We know nothing of God out of Christ. We may be out of Christ ourselves, and then indeed, as a consuming fire, the very presence of God would destroy us. But as He is known to us who are in Christ, He is a God who will not tolerate any evil, anything inconsistent with Himself.
Fire and love are not opposites
Set beside "God is love," this verse can sound like a contradiction. One writer argues the two belong together, and uses a homely picture to show it.
The Love of GodIt seems very different to say, "our God is a consuming fire" and "God is love," but really these statements go together. Our God is a consuming fire because He is love, because there must be an intense action that both preserves the good and opposes the evil. Can God be indifferent to what would stop His love being known? Impossible. How does a mother feel towards the snake that would bite her child?... Our jealousy comes from selfishness, but God's jealousy comes from complete unselfishness. If we know the love of God, we are thankful for every one of His attributes. If not, even His kindness fills us with dread.
What the fire burns in His own people
Hebrews 12 speaks of a shaking that removes what can be shaken. The fire has a target, and it is not the believer.
Hamilton SmithLet us not forget that, though we know God in grace, still, "our God is a consuming fire." He will burn everything that is not of Himself, whether it be flesh in His people or a creation defiled by sin.
That distinction shapes how God deals with those He loves. He forgives fully, yet He will not leave sin unaddressed in their lives.
C. H. MackintoshHe cannot approve unjudged evil in His people. He can pardon, heal, restore, and bless; but He will not tolerate evil. "Our God is a consuming fire."
For those who turn away from grace
The verse also closes a warning to anyone who refuses the One speaking from heaven.
J. G. BellettFrom the fires of Sinai there was a relief, by turning and taking refuge in Christ; but there is no relief if God's relief is despised. If you turn away from the relief this age brings in, there is no more relief. "Our God is a consuming fire."
Summary
- Fire is holiness. Not temper, but the necessary reaction of God's nature to everything opposed to His will.
- Fire is love. He consumes because He loves — preserving the good, resisting whatever would harm it.
- Fire is ours. The verse says our God, the God known in grace; He has not changed in His hatred of sin.
- Fire refines. In His people He burns what is not of Himself, forgiving fully while refusing to leave evil unjudged.
- Fire warns. Refuse the shelter grace offers, and there is nothing left but the fire itself.
