At times I have know people who treat God like a vending machine. They see something they want and they put what they feel the price should be in. Then they expect their desire to just fall out. If they want something greater, they do a little more. If they don’t get what they want, they might put a little more in or maybe bang on the machine. We need to seek the face of God and pray for His will to be done.
1 John 5:14-15 (NIV)
14 This is the confidence we have in approaching God: that if we ask anything according to his will, he hears us.
15 And if we know that he hears us--whatever we ask--we know that we have what we asked of him.
