God cannot learn anything, He already knows everything.

Prayer is the rope that pulls God and man together, but it doesn’t pull God down to us, it pulls us up to Him.

WHY PRAYERS ARE NOT ANSWERED

There is a quip which some of my colleagues seem to appreciate more than I do: God always answers your prayers, but sometimes His answer is No. This strikes me as bad theology and bad psychology to boot. What do we accomplish by saying to ourselves, and to our children, that the things we prayed for were possible but that we didn’t deserve them? God could have sent you a puppy but He decided not to. "God could have saved Daddy from  sickness, as you prayed, but He had His reasons for not doing it. Does such an answer increase either our affections for God or our respect for ourselves? It would be better to remember that a prayer is not a request and that, most of the time, our prayers require no answer. If we hope for sunshine on the day of our outing and the sun does shine, it is not because our prayers have been answered any more than showers would indicate our unworthiness. Rain and clear skies are matters of meteorology, not morality.

In fact, no prayer which treats of changes in the world outside is ever really answered. Only when we pray for a change within ourselves is it possible for our act of prayer to influence the results. For the members of a football team to pray that they play to the limits of their ability, that their minds be free of tension and distraction on the day of the big game, is perfectly appropriate. For them to pray that the other team plays badly is not only mean-spirited, but even worse, ineffective. And the fan watching the game on television, praying for his team’s victory, should be under no illusion that his invocations of Heavenly aid will affect the score in any way.

Only the man who prays about what sort of person he wants to become, the man who prays for clarity of understanding and strength of purpose, has a chance of getting a response to his prayer. He invokes not the Father in Heaven, who evaluates all of his requests and stamps each of them yes or no, but his own better self, and if he prays sincerely, the answer may be close at hand.
