If we assume that you are right, who defines what "good" is: some smarmy TV evangelist who takes badly needed pennies from his viewers while driving around in a limousine and wearing $500 suits? A book which was devised 2000 years ago and which has been edited and adjusted to justify a repressive religion? Or perhaps some insane jihadist who hates anyone who's not as insane as he is?
No, if God exists, an assumption I'm not ready to make, he's certainly not interested in the goings-on on this ball of dirt. For mankind to assume that God is so consumed with our lives that he would change things around just because someone prays to him is the height of egotism.
