All 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 PiperCHRISTIAN LIVING MOVES from what God has freely done for us in Christ to what we should freely do for others.
John PiperThe purpose of the Lord's Supper is to receive from Christ the nourishment and strength and hope and joy that come from feasting our souls on all that He purchased for us on the cross, especially His own fellowship.
John PiperDon't wait for a feeling or love in order to share Christ with a stranger. You already love your heavenly Father, and you know that this stranger is created by Him, but separated from Him... so take those first steps in evangelism because you love God. It is not primarily out of compassion for humanity that we share our faith or pray for the lost; it is first of all, love for God.
John Piper
