Our Tip Tract is not an alternative to giving money or an excuse for Christians to be miserly.
In fact, it's printed on an envelope that is just the right size to hold dollar bills, and we encourage you to be generous with what you put inside! The point here is that, in addition to giving money, we can leave something that is of much more value - a list of simple tips that point a person to true salvation in Jesus Christ.
Leaving money without any reference to Jesus is a wasted opportunity. But leaving a tract without any money is just plain stingy.
