“There was no rain before the Flood.”
This is not a direct teaching of Scripture, so again there should be no
dogmatism. Genesis 2:5–6 at face value teaches only that there was no
rain at the time Adam was created. But it doesn’t rule out rain at any later
time before the Flood, as great pre-uniformitarian commentators such as John Calvin pointed out. A related
fallacy is that the rainbow covenant of Genesis 9:12–17 proves that there were no rainbows before the
Flood. As Calvin pointed out, God frequently invested existing things with new
meanings, e.g., the bread and wine at the Lord’s Supper.
