If you criticize how someone else uses money, you have a wrong relationship with money.
This expresses itself in many ways.
You could be upset with your boss having nice things because you think you should be paid more. You could be upset with how your church is spending money. Perhaps your pastor lives in too nice of a house, according to your standards.
I could go on, but you get the point.
One of the ten commandments is, "Thou shalt not covet." What is covetousness?
Coveting is when you get your thoughts into someone else's bank account.
Any time your thoughts venture into someone else's finances, shut it down. Throw that type of thinking in the trash. Get rid of covetousness.
I'm helping you learn how to see money the way God does— so that He can prosper you like He wants to.
