In Elder Eyring’s devotional talk at BYU Idaho (September 2001) he mentioned being frugal. I know he was referring to BYU-Idaho operating on a tight budget but he seemed to want us to apply it in our daily lives as well.
He said, “You want to have a beautiful place that you live in someday in your family. You want to have things as nice as you can have them. But I'll tell you something. One of the things that you do is to always look at every nice thing you have as God's and treat it very, very carefully…
In addition, you will not ever, ever ask for more than you need…. Now I testify to you that that blessing is both a practical one and a spiritual one. It's practical because then the Lord will provide when we do need something, and He'll provide generously because He trusts us. But it has another benefit as well. I testify to you that that spirit of sacrifice, that spirit of trying to give just a little bit more and ask a little less brings down the powers of heaven.
