Wherever your treasure is, there the desires of your heart will also be. (Luke 12:34 NLT)
Look at your check book and categorize the amount you spend on the necessities of life: housing, cars, utilities, food, clothes, taxes, insurance, etc. Now, consider where the rest of your income is spent and put those totals in broad categories: recreation, investments, church, etc. Any Christian willing to look honestly at how their money is spent will soon discover why they love some things more than others. They'll also see where lots of money is wasted on excessive, temporal pursuits when they could be laying up treasures in Heaven.
