Genesis 7:19 And the waters prevailed exceedingly upon the earth; and all the high hills, that were under the whole heaven, were covered. 20 Fifteen cubits upward did the waters prevail; and the mountains were covered.
[Patriarchs & Prophets pp 108>109] God saw that the more He enriched and prospered sinful men, the more they would corrupt their ways before Him. The treasures that should have led them to glorify the bountiful Giver had been worshiped, while God had been dishonored and despised. The earth presented an appearance of confusion and desolation impossible to describe. The mountains, once so beautiful in their perfect symmetry, had become broken and irregular. Stones, ledges, and ragged rocks were now scattered upon the surface of the earth.
In many places hills and mountains had disappeared, leaving no trace where they once stood; and plains had given place to mountain ranges. These changes were more marked in some places than in others. Where once had been earth's richest treasures of gold, silver, and precious stones, were seen the heaviest marks of the curse. And upon countries that were not inhabited, and those where there had been the least crime, the curse rested more lightly. At this time immense forests were buried. These have since been changed to coal, forming the extensive coal beds that now exist, and also yielding large quantities of oil. The coal and oil frequently ignite and burn beneath the surface of the earth.
Thus rocks are heated, limestone is burned, and iron ore melted. The action of the water upon the lime adds fury to the intense heat, and causes earthquakes, volcanoes, and fiery issues. As the fire and water come in contact with ledges of rock and ore, there are heavy explosions underground, which sound like muffled thunder. The air is hot and suffocating. Volcanic eruptions follow; and these often failing to give sufficient vent to the heated elements, the earth itself is convulsed, the ground heaves and swells like the waves of the sea, great fissures appear, and sometimes cities, villages, and burning mountains are swallowed up.
Luke 21:10 Then said he unto them, Nation shall rise against nation, and kingdom against kingdom: 11 And great earthquakes shall be in divers places, and famines, and pestilences; and fearful sights and great signs shall there be from heaven.
May God add His blessing to the study of His word. “Good night” and God bless!
