How do we know that Jesus is the consuming fire mentioned in the Bible?

In Hebrews 12:29, we read, 'For our God is a consuming fire,' which points to the holy and purifying nature of Christ. Throughout the Bible, fire is often used as a metaphor for purity, judgment, and the presence of God. In the context of the sermon and referring to Malachi 3:2, it is evident that Christ, as the refiner's fire, purifies His people from sin and the impurities of this world. He comes with fiery words that demolish falsehoods, much like a fire that consumes all that is not holy. The idea of Christ being a consuming fire illustrates His role in both judgment for the wicked and sanctification for believers.
