In the first place preach, and in the second place preach, and in the third place preach.
Believe in preaching the love of Christ, believe in preaching the atoning sacrifice, believe in preaching the new birth, believe in preaching the whole council of God. The old hammer of the gospel will still break the rock in pieces; the ancient fire of Pentecost will still burn among the multitude. Try nothing new, but go on with preaching, and if we all preach with the Holy Ghost sent down from heaven, the results of preaching will astound us.
Have great hope yet, brothers, have great hope yet, despite yon shameless midnight streets, despite yon flaming gin-palaces at the corner of every street, despite the wickedness of the rich, despite the ignorance of the poor. Go on; go on; go on; in God’s name go on, for if the preaching of the gospel does not save men, nothing will. If the Lord’s own way of mercy fails, then hang the skies in mourning, and blot out the sun in everlasting midnight, for there remaineth nothing before our race but the blackness of darkness. Salvation by the sacrifice of Jesus is the ultimatum of God. Rejoice that it cannot fail. Let us believe without reserve, and then go straight ahead with the preaching of the Word.
The Soul Winner, Charles Spurgeon, p 179
