Charles Spurgeon, from The Pastor in Prayer:
Lord, convert our friends that still remain unsaved. Oh, mighty power of God, let none come into this house, even accidentally and casually, without receiving some devout impression. May the Spirit of God work mightily by our ministry, and the ministration of all His servants now present, whether in the Sabbath school, or in the streets, or in the lodging-houses, or from door to door, or when they privately speak to individuals.
Oh, glorify Thyself in us! Dear Saviour, we pray Thee come and mark us all distinctly with the blood mark, as being wholly Thine, and henceforth may we say with Paul, “Let no man trouble me; for I bear in my body the marks of the Lord Jesus.” As we have been buried with Thee by baptism into death, so would we be dead to all the world and only live for Christ. God grant it may be so, and we will glorify Thee in life, and death, and forever.
