Do you ever cry out to the Lord, "How long, 0 Lord? How long till you vindicate your cause in the earth? How long till you rend the heavens and come down with power on your church? How long till you bring forth victory among all the peoples of the world?" Is not his answer plain: "When my people cry to me day and night, I will vindicate them, and my cause will prosper among the nations." The war will be won by God. He will win it through the gospel of Jesus Christ. This gospel will run and triumph through prevailing prayer-so that in everything God might be glorified through Jesus Christ. John Piper. Let the Nations Be Glad!: The Supremacy of God in Missions (p. 70). Kindle Edition.
