Most people quickly agree that "Yes, I want to save money" but then the next thought is "How can I save money I don't have?" It's so hard to buy extra and save money for preparation purposes when your living expenses are already tight or maxed out. However, the Lord does not give commandments without giving a way to fulfill them. There are tools that you can use to design your goals in how to save a little here and a little there. Remember, save a little at a time. If you can shop sales and save $5 grocery shopping, put that money aside in your saving reserve. Seperate your savings from your expeditures so you don't accidently use it. Some other things to research and think about:
