This collection of missions-oriented sermons by John Piper, compiled by Desiring God, challenges you to consider and cultivate a holy ambition to preach Christ where he has not yet been named.

The apostle Paul had a holy ambition - to preach the gospel to peoples who had never heard. He ached to proclaim Jesus where he had not yet been named. So today, missionaries cross cultures, learn languages, and pour out their lives in word and deed to break through thousands of years of darkness and the reign of Satan over a people who do not know the King of kings and the Savior of the world. Missionaries go to, and minister among, peoples who otherwise have little to no access to the saving news of Jesus' life, death and resurrection.

And since Jesus' Great Commission to make disciples of all nations is still in effect - and since there are thousands of peoples today who have never heard of him - every church should pray that God would not only make all of us evangelists among our own people, but also that he would raise up from among us missionaries to take the gospel where it has never gone before.
