"And Noah did according unto all that the LORD commanded him. And Noah was six hundred years old when the flood of waters was upon the earth. And Noah went in, and his sons, and his wife, and his sons' wives with him, into the ark, because of the waters of the flood." (Genesis 7:5-7)
Not much is said in the Bible about Noah's wife or daughters-in-law. We don't even know their names, their ages, or how long they were married. We do, however, know this: these four ladies made a choice to enter the ark. In the midst of evil and wickedness, these ladies were presented with a choice and choose "that one needful thing".
Put yourself in their shoes. If their genealogy was anything like the rest of the people in Genesis, then their mothers, fathers, brothers, sisters, aunts, uncles, cousins, nephews, nieces, grandparents, great-grandparents, great-great-grandparents, friends, and neighbors were many but were also "evil and wicked". The choice they had to make wasn't easy.
Which lady in her right mind would wish to be utterly cut off from her family? How about being mocked and jeered by the very girl with whom you shared girlhood dreams? What would it be like seeing your mama from a distance, unable to talk to her? For years?
The choice these ladies of faith had to make was clear to them. Regardless of their emotions, they could not, would not, forsake the one true God. Without being able to see the heartache future years would bring, they chose to follow their God, follow their husbands, and as they went into the ark that day, they had no regrets.
Just imagine what it was like that day as they stepped out of the ark. All around them everything was dead. The world was so different from when they stepped into the ark. But then God spoke...
"And God said, This is the token of the covenant which I make between me and you and every living creature that is with you, for perpetual generations: I do set my bow in the cloud, and it shall be for a token of a covenant between me and the earth. And it shall come to pass, when I bring a cloud over the earth, that the bow shall be seen in the cloud: And I will remember my covenant, which is between me and you and every living creature of all flesh; and the waters shall no more become a flood to destroy all flesh. And the bow shall be in the cloud; and I will look upon it, that I may remember the everlasting covenant between God and every living creature of all flesh that is upon the earth." (Genesis 9:12-16)
