The following comes from a sermon preached by Benjamin B. Warfield on the text of John 3:16 entitled, "God's Immeasurable Love":

You must not fancy, then, that God sits helplessly by while the world, which He has created for Himself, hurtles hopelessly to destruction, and He is able only to snatch with difficulty here and there a brand from the universal burning.  The world does not govern Him in a single one of its acts: He governs it and leads it steadily onward to the end which, from the beginning, or ever a beam of it had been laid, He had determined for it....Through all the years one increasing purpose runs, one increasing purpose: the kingdoms of the earth become ever more and more the Kingdom of our God and His Christ.  The process may be slow; the progress may appear to our impatient eyes to lag.  But it is God who is building: and under His hands the structure rises as steadily as it does slowly, and in due time the capstone shall be set into its place, and to our astonished eyes shall be revealed nothing less than a saved world.
