[God] waited in the days of Noah, while the ark was being prepared, in which a few, that is, eight souls, were saved through water.
1 Peter 3:20
Genesis 6:9 through 8:22 tells how Noah and his family were delivered through the Flood. They were the only people who believed God’s warning of the coming worldwide catastrophe. As a result, all mankind was drowned in judgment, except them.
Noah preached the righteousness of God for the hundred and twenty years it took him to build the ark. The size of a modern ocean liner (Gen. 6:15), it was sure to attract attention. But it must have been discouraging to build that ark and preach its meaning for over a century, yet have only your immediate family believe.
Noah’s tremendous effort was spent on building a vessel he would spend only a year using, but those eight people were safe from God’s judgment when it came. The ark served as their shelter from the encompassing judgment of God. What a graphic illustration of salvation!
