Noah's ark was saved by God.

In Gen 6:1-7, while Noah’s generation was falling into the worst abuses of the image of God in human history, Noah found favor or grace with God. Today, especially in light of Gen 6:9, a reader may be tempted to believe Noah earned this favor through righteous and blameless living. Allen Ross, in his commentary on Genesis, points out that this Hebrew word for favor most often means not only an unmerited grace, but a favor given when one is in a position to deserve the opposite, i.e., judgment.
