Prayer?

[Undeceived]

Or there's the prayer we should be praying: "Your will be done." If we conform our desires to God's will, our prayers will always be answered. It's healthier to change an outlook than it is to blindly hope for gifts. We need to meet God partway, becoming "Sons", rather than treating Him as an arbitrary vending machine.

... are you joking?

Let's put it this way. You're a father. Your 2-year-old son refuses to change his mind about anything, ever. You plead with him, telling him you are more experienced and know what's best for him. He demands ice cream every day, won't thank you for it, and is quickly becoming the most unhealthy child on the planet. What would you (God) do?

"What is Gods will?", "Wouldn't Gods will occur anyway?"

In our case, God's will is what He knows is best for us. Our free will allows us to do something different entirely. The outcome will be negative.
There is a broader "will" of God, which basically means nothing will happen without God seeing and allowing it.
