1 Timothy 6:10, the verse about the love of money being the root of all kinds of evil, is always assigned to rich people. It's a rich people verse because all of those rich people need to know that they better not get too attached to their massive wealth. But the truth is, you don't have to have money to love money.
In trying to be thrifty, I've got to be careful that my motivation isn't just to have money. Am I being wise with my money so I can be generous, debt-free, and prepared for the future, or just so that I can have more wealth and possessions? Being frugal is often seen as virtuous, and it often is, but I have to look past appearances and into my own heart and ask myself what my motivations are.
