The best thing about Randy Alcorn's The Treasure Principle is his six points. They were a great impetus to changing my attitudes:
Principle #1- God owns everything. I am His money manager.
Principle #2- My heart always goes where I put God's money.
Principle #3- Heaven, not Earth, is my home.
Principle #4- I should live for the line (eternity), not the dot(short life on earth).
Principle #5- Giving is the only antidote for materialism.
Principle #6- God prospers me not to raise my standard of living, but to raise my standard of giving.
