Charles Spurgeon Commentary Hebrews 12:25-29

"See that ye refuse not him that speaketh. For if they escaped not when they refused him that warned [them] on earth, much more [shall not] we [escape] who turn away from him that [warneth] from heaven: whose voice then shook the earth: but now he hath promised, saying, Yet once more will I make to tremble not the earth only, but also the heaven. And this [word], Yet once more, signifieth the removing of those things that are shaken, as of things that have been made, that those things which are not shaken may remain. Wherefore, receiving a kingdom that cannot be shaken, let us have grace, whereby we may offer service well-pleasing to God with reverence and awe: for our God is a consuming fire." — Hebrews 12:25-29 (ASV)

See that ye refuse not him that speaketh. For if they escaped not who refused him that spake on earth, much more shall not we escape, if we turn away from him that speaketh from heaven: whose voice then shook the earth: but now he hath promised, saying, Yet once more, I shake not the earth only, but also heaven. And this word, yet once more signifieth the removing of those things that are shaken, as of things that are made, that those things which cannot be shaken may remain. Therefore we receiving a kingdom which cannot be moved, let us have grace, whereby we may serve God acceptably with reverence and godly fear: for our God is a consuming fire.

Not "God out of Christ," as some say, but God in Christ, God anyhow is a consuming fire, and we should each one pray, "Consuming fire, refining fire, go through my heart and purge me of all that can be consumed! Holy Spirit, drive out of me all that can be shaken and removed, that only your abiding kingdom may remain in me, and yours shall be the praise and the glory for ever! Amen."
