Theophylact of Ohrid, on Heb 12:29

“For our God is a consuming fire.”

“Having shown, on the one hand, that the Old Testament events inspire fear, and on the other, that in the New Testament there is nothing of the sort, he, lest they treat the gentleness with contempt, says: let us offer gratitude to God with reverence and fear. For the soul, giving in to despair during calamities, loses its shame. Or: our service must be performed with reverence and fear. For our God is a fire, and therefore we must have fear, lest He destroy us as negligent and indifferent. For it says: let the sons of Israel be reverent. This also provides them consolation, namely that we have such a God Who is able to consume our enemies.”
