Each time, before you intercede, be quiet first, and worship God in His glory. Think of what He can do, and how He delights to hear the prayers of His redeemed people. Think of your place and privilege in Christ, and expect great things!
Andrew MurrayGod cannot hear the prayers on our lips often because the desires of our heart after the world cry out to Him much more strongly and loudly than the our desires for Him.
