Contradiction with Genesis 8:22
This verse states that while the earth remains, seasons and cycles will not cease, suggesting continuity of the earth's physical state, whereas Revelation 16:20 speaks of drastic changes to the earth.
Genesis 8:22: While the earth remaineth, seedtime and harvest, and cold and heat, and summer and winter, and day and night shall not cease. [While...: Heb. As yet all the days of the earth]
Contradiction with Isaiah 54:10
It says the mountains shall depart, and the hills be removed, yet God's kindness shall not depart, indicating stability contrary to the upheaval described in Revelation 16:20.
Isaiah 54:10: For the mountains shall depart, and the hills be removed; but my kindness shall not depart from thee, neither shall the covenant of my peace be removed, saith the LORD that hath mercy on thee.
Contradiction with Psalm 104:5
Describes God laying the earth's foundations so it should not be moved, which contradicts the upheaval in Revelation 16:20.
Psalm 104:5: [Who] laid the foundations of the earth, [that] it should not be removed for ever. [Who...: Heb. He hath founded the earth upon her bases]
Contradiction with Ecclesiastes 1:4
States that the earth abides forever, which opposes the notion of mountains and islands fleeing as described in Revelation 16:20.
Ecclesiastes 1:4: [One] generation passeth away, and [another] generation cometh: but the earth abideth for ever.
Contradiction with Jeremiah 31:35-36
God's promise that the ordinances of the heavens and earth would remain, contradicting the massive earth changes in Revelation 16:20.
Jeremiah 31:35-36: Thus saith the LORD, which giveth the sun for a light by day, [and] the ordinances of the moon and of the stars for a light by night, which divideth the sea when the waves thereof roar; The LORD of hosts [is] his name:
Contradiction with Psalm 46:2
While acknowledging the possibility of earth's changes, it affirms God's presence and help, different from the overwhelming nature of destruction in Revelation 16:20.
Psalm 46:2: Therefore will not we fear, though the earth be removed, and though the mountains be carried into the midst of the sea; [midst...: Heb. heart of the seas]
Contradiction with Hebrews 12:27
Talks about removing things that can be shaken, implying permanence for certain things, in contrast to the disappearance of every mountain and island.
Hebrews 12:27: 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. [are shaken: or, may be shaken]
Paradox #1
Revelation 16:20 mentions all the islands and mountains disappearing, which can contradict scientific understanding of Earth’s geological processes. Islands and mountains are formed and changed over millions of years through tectonic activity, and such a sudden disappearance isn't consistent with natural geological events as understood by science.
