Lastly, the effect of the voice of God: When God spoke His law from Sinai, “the whole mount quaked greatly.” 3Exodus 19:18. “The earth shook, the heavens also dropped at the presence of God; even Sinai itself was moved at the presence of God, the God of Israel.” 4Psalm 68:8. “The earth trembled and shook.” 6Hebrews 12:26. But even greater will be the effect of that voice at the second advent. From Sinai, His “voice then shook the earth; but now hath he promised, saying: Yet once more I shake not the earth only, but also heaven.” “The heavens shall pass away with a great noise,” for “the powers of the heavens shall be shaken.” EVCO 287.3
Wonderful likenesses we find between the coming of the Lord to give the law at Sinai, and His coming to judgment in the end of the world; and we shall find as we study that the likenesses are by no means accidental. EVCO 287.4
