Pr 31:21 She is not afraid of the snow for her household: for all her household are clothed with scarlet.
She wasn't concerned about the weather. Whatever came, they were prepared.
Here in south Louisian, we don't get alot of snow. But we do get hurricanes. And while we don't have to dress warmly when one comes (it is usually very hot here when we get one), we do have to have preparations made for food when one hits. We could be without electricity for a week or more.
I read this verse as a call to readiness, no matter what comes our way, or when it comes our way.
Oh, and the last part, about being clothed with scarlet. I see that as a call to be clothed with the blood of Jesus.
Oh, that we might walk daily under His precious blood. The precious blood He willingly gave so that I, and you if you have received Him as your Savior, might be called a daughter of the Living God!
