Andrew Murray said this quote

Ask and you shall receive; everyone that asks receives.  This is the fixed eternal law of the kingdom:  If you ask and receive not, it must be because there is something amiss or wanting in the prayer. Hold on; let the Word and Spirit teach you to prat aright, but do not let go the confidence he seeks to waken:  Everyone who asks receives....Let every learner in the school of Christ therefore take the Master's word in all simplicity....Let us beware of weakening the word with our human wisdom.
