God is not obligated to our prayers as much as He is obligated to His word.
When our praying resembles complaining, there will be very little response from heaven. At this moment, it is best to pause and ask God for the right prayer or the right questions.
When we pray His WORD, He is bound by His Word to move. The right heart and motive in our prayers reveal our motives. Is the prayer actually driven by fear? Anger?
God is waiting to hear us speak HIS Word out of our hearts and mouths.
