David Platt, Radical: Taking Back your Faith from the American Dream (Colorado Springs: Multnomah, 2010), 156, speaks of God’s plan to get the gospel to the nations in Romans 10:14-15:
So there you have it—the simple divine plan for taking the gospel to all peoples of the world.
God sends his servants.
His servants preach.
People hear.
Hearers believe.
Believers call.
Everyone who calls is saved.
Now look back at this progression and ask one question: Is there any place where this plan can break down? Think about it. Obviously everyone who calls on the name of the Lord will be saved.No breakdown there. Everyone who believes will call.Many who hear (not all, but many) will believe. People will hear the gospel when we preach it to them. And God is most definitely still in the business of sending his servants. That means there is only one potential breakdown in this progression—when servants of God do not preach the gospel to all peoples. We are the plan of God, and there is no plan B.
Of course, God has the power to write the gospel in letters across the clouds so that all people can learn about Jesus and believe in him. But in his infinite wisdom, he has not chosen this route. Instead he has chosen to use us as ambassadors who carry the gospel to people who have never heard the name of Jesus.
