Gary Thomas writes in Christianity Today:

Thinking about eternity helps us retrieve [perspective]. I'm reminded of this every year when I figure my taxes. During the year, I rejoice at the paychecks and extra income, and sometimes I flinch when I write out the tithe and offering. I do my best to be a joyful giver, but I confess it is not always easy, especially when there are other perceived needs and wants. At the end of the year, however, all of that changes. As I'm figuring my tax liability, I wince at every source of income and rejoice with every tithe and offering check--more income means more tax, but every offering and tithe means less tax. Everything is turned upside down, or perhaps, more appropriately, right-side up. I suspect judgment day will be like that.
