Discussing this forum with my wife recently (she thinks I'm wasting my time, but anyway...), she had this analagy:
Often when we encounter a homeless person who asks for money, our inclination is to instead buy them a meal. Not what they asked for, but what we decided was best for them.
It's possible to apply that to God with any sort of prayer request - He will do what He knows to be in our best interests, even if we don't agree or see the reason.
Just a thought. Have a good weekend.
