And the water prevailed more and more upon the earth, so that all the high mountains everywhere under the heavens were covered.
Genesis 7:19 (NASB)
If you believe me when I tell you that the Flood is a story about God removing our sins by way of trials that purify us, you'll understand "high mountains" as the "proud places" (the Hebrew phrase is "lofty hills") in our lives, and you'll see that God will cover those, too.
He will redeem us.
