It is our nature to expect that WE know better. Many times "God's economy" is just the opposite of what we would expect.
It is hard for us to get past our own expectations and rely, by faith alone, on what God tells us. Sometimes it seems too simple. We think "There's got to be more to it than THAT! Other times we say, "Here, let me help you with that." We're just trying to do our part... we think "I have to make an effort of some kind, otherwise it's not FAIR."
Someone else already paid the price. Accept the gift FIRST. THEN we'll talk about your mission and purpose.
Well and truly stated.
