So, you have three possibilities in world missions. You can be a goer, a sender, or disobedient. The Bible does not assume that everyone goes. But it does assume that the ones who do not go care about goers and support goers and pray for goers and hold the rope of the goers.
John PiperTherefore bread was created for the glory of Christ. Hunger and thirst were created for the glory of Christ. And fasting was created for the glory of Christ. Which means that bread magnifies Christ in two ways: by being eaten with gratitude for his goodness, and by being forfeited out of hunger for God himself. When we eat, we taste the emblem of our heavenly foodโthe Bread of Life. And when we fast we say, โI love the Reality above the emblem.โ In the heart of the saint both eating and fasting are worship. Both magnify Christ.
John PiperThe deepest need that you and I have in weakness and adversity is not quick relief, but the well-grounded confidence that what is happening to us is part of the greatest purpose of God in the universe - the glorification of the grace and power of his Son - the grace and power that bore Him to the cross and kept him there until the work of love was done.
John Piper
