Charles Spurgeon on preaching the gospel:
If a man be truly called of God to the ministry, I will defy him to withhold himself from it. A man who has really within him the inspiration of the Holy Ghost calling him to preach cannot help it. He must preach. As fire within the bones, so will that influence be until it blazes forth. Friends may check him, foes criticise him, despisers sneer at him, the man is indomitable; he must preach if he has the call of heaven. All earth might forsake him; but he would preach to the barren mountain-tops. If he has the call of heaven, if he has no congregation, he would preach to the rippling waterfalls, and let the brooks hear his voice. He could not be silent.
