God's global aim in creation and redemption is not only the glory of his name, but also the gladness of the peoples.
John PiperAll of history is moving toward one great goal, the white-hot worship of God and His Son among all the peoples of the earth. Missions is not that goal. It is the means. And for that reason it is the second greatest human activity in the world.
John PiperWhen you are deeply peaceful and confident that, because of Christ, God will bring you safely to his eternal kingdom and be the all-satisfying Treasure of your life forever, then you are free to see the truth, and love the truth, and speak the truth no matter what, and joyfully spread a passion for the truth whose name is Jesus.
John PiperThere will be no passion to draw others into our worship where there is no passion for worship.
John PiperWe can say that true gratitude does not give rise to the debtor's ethic because it gives rise to faith in future grace. With true gratitude there is such a delight in the worth of God's past grace, that we are driven on to experience more and more of it in the future...it is done by transforming gratitude into faith as it turns from contemplating the pleasures of past grace and starts contemplating the promises of the future.
