I came across a wonderful post that addresses the above question.
I agree with her assertion that Scripture calls us to be prepared.
I do believe that God wants us to be prudent in our decisions concerning the future. I believe that Proverbs 31:21 points out that one of my duties as a woman is to ensure that our family is prepared. That verse states:
"She is not afraid of snow for her household, for all her household is clothed with scarlet."
To me, this means that I should take precautions before an event occurs so that my household has nothing to fear. Now, whether that event is an ice storm or an economic collapse..the premise is still the same. I have a Scriptual obligation to make sure my family is prepared.
Just some thoughts..things to think about...
