Hebrews 12:29

The motive enforcing this duty is no less terrible than that given to Israel under the law, obliging their obedience to that covenant dispensation, Deuteronomy 4:23,24: The Lord thy God is a consuming fire, even a jealous God. He that was so respecting the transgression of the legal, will much more be so as to this gospel covenant. God Almighty, the most gracious, and yet the most just Being, their own God by covenant obtestation; yet will be to them, if they break his covenant, and do not, through Christ, acceptably serve him with reverence and godly fear, as fire consuming them. His gospel law, in the contempt of it, will be as the fiery law at Sinai, adjudging such sinners unto fire unquenchable, Hebrews 10:27; compare Matthew 2:12; Matthew 3:41 2 Thessalonians 1:7.
