I am a big fan of Charles Haddon Spurgeon, so it should come as no surprise that I tracked down a Spurgeon sermon on Nehemiah. You can read it for yourself here.
“What are your difficulties, dear friend, in coming to the mercy seat? What hindrance lies in your way? Let nothing obstruct your approach to the throne of grace. Turn all stumbling-stones into stepping-stones; and come, with holy boldness, and say, notwithstanding all opposition, ‘never the less, we made our prayer unto our God.'”
