Orange Juice That Glorifies God

Today I read a very nice article entitled "How To Drink Orange Juice to the Glory of God" by John Piper. The focus was on how to do trivial things for the glory of God, thus fulfilling 1 Corinthians 10:31's command to do everything for the glory of God. Piper takes the stand, as I do, that anything not done explicitly for the glory of God is sinful, and therefore no non-Christian can do anything morally good. It was not an exhaustive defense, but it was nice to read none-the-less. Enjoy.
