"A young engineer was being examined, and this question was put to him: 'suppose you have a steam pump, constructed for a ship, under your supervision, and you know that everything is in perfect order, yet, when you throw out the hose, it will not draw; what should you think?' 'I should think, sir, that there must be a defect somewhere.' 'But such a conclusion is not admissible; for the supposition is that everything is perfect, and yet the pump will not work.' 'Then, sir,' replied the student, 'I should look over the side of the ship to see if the river had run dry.' Even so it would appear that if true prayer is not answered the nature of God must have changed.” - Spurgeon's Sermon Notes
