What is the real winning of a soul for God? So far as this is done by instrumentality, what are the processes by which a soul is led to God and to salvation? I take it that one of its main operations consists in instructing a man that he may know the truth of God. Instruction by the gospel is the commencement of all real work upon men’s minds. “Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost: teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the world.” Teaching begins the work, and crowns it, too.
