Many of us have heard the phrase God is a comsuming fire many times and often used incorrectly. However, have you ever pondered the portion of Scriptures just before that? It has alot to do with the Law and the New Covenant.
Hebrews 12:18-29 (ESV)
18 For you have not come to what may be touched, a blazing fire and darkness and gloom and a tempest
19 and the sound of a trumpet and a voice whose words made the hearers beg that no further messages be spoken to them.
20 For they could not endure the order that was given, “If even a beast touches the mountain, it shall be stoned.”
21 Indeed, so terrifying was the sight that Moses said, “I tremble with fear.”
22 But you have come to Mount Zion and to the city of the living God, the heavenly Jerusalem, and to innumerable angels in festal gathering,
23 and to the assembly of the firstborn who are enrolled in heaven, and to God, the judge of all, and to the spirits of the righteous made perfect,
24 and to Jesus, the mediator of a new covenant, and to the sprinkled blood that speaks a better word than the blood of Abel.
25 See that you do not refuse him who is speaking. For if they did not escape when they refused him who warned them on earth, much less will we escape if we reject him who warns from heaven.
26 At that time his voice shook the earth, but now he has promised, “Yet once more I will shake not only the earth but also the heavens.”
27 This phrase, “Yet once more,” indicates the removal of things that are shaken—that is, things that have been made—in order that the things that cannot be shaken may remain.
28 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,
29 for our God is a consuming fire.
Hebrews 12:18-29 (KJV)
18 For ye are not come unto the mount that might be touched, and that burned with fire, nor unto blackness, and darkness, and tempest,
19 And the sound of a trumpet, and the voice of words; which voice they that heard intreated that the word should not be spoken to them any more:
20 (For they could not endure that which was commanded, And if so much as a beast touch the mountain, it shall be stoned, or thrust through with a dart:
21 And so terrible was the sight, that Moses said, I exceedingly fear and quake:)
22 But ye are come unto mount Sion, and unto the city of the living God, the heavenly Jerusalem, and to an innumerable company of angels,
23 To the general assembly and church of the firstborn, which are written in heaven, and to God the Judge of all, and to the spirits of just men made perfect,
24 And to Jesus the mediator of the new covenant, and to the blood of sprinkling, that speaketh better things than that of Abel.
25 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:
26 Whose voice then shook the earth: but now he hath promised, saying, Yet once more I shake not the earth only, but also heaven.
27 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.
28 Wherefore we receiving a kingdom which cannot be moved, let us have grace, whereby we may serve God acceptably with reverence and godly fear:
29 For our God is a consuming fire.
