25 See that you do not refuse Him who speaks. For if they did not escape who refused Him who spoke on earth, much more shall we not escape if we turn away from Him who speaks from heaven, 26 whose voice then shook the earth; but now He has promised, saying, “Yet once more I shake not only the earth, but also heaven.” (Hebrews 12:25–26, NKJV)
There are terrible consequences for rejecting the word of God. The ground shook when God spoke the Ten Commandments to Israel from Mt. Sinai (Exodus 19:18). Yet, Israel rejected God’s word, and made a golden calf to worship in direct violation of His commandments (Exodus 20:1-6; 32:1-7). About 3,000 men died that day as punishment for their sin (Exodus 32:28, 34-35). There is an unmistakable lesson for us from this event. We will not escape punishment if we reject God’s word that He has spoken to us from heaven “in His Son,” by the New Testament Scriptures (Hebrews 1:2; 2 Timothy 3:16-17). The Day of Judgment will remove heaven and earth. Only His kingdom will survive His awesome judgment (Hebrews 12:26-28). The words and wisdom of men will never prepare you to escape divine wrath against sin. But, the gospel of Jesus Christ will; it is God’s power to save you (Romans 1:16). Believe God’s word and obey the Lord Jesus, to “have grace, by which we may serve God acceptably with reverence and godly fear. For our God is a consuming fire” (Hebrews 12:28-29).
