The most simple (and most important) answer is because there are souls in Vienna who need to hear the good news.

There are nearly 2 million people in Vienna and less than 100 members of the church of Christ.

The ultimate goal is to see the European continent evangelized. Strategic church planting can accomplish this task and Vienna is a city vitally important and influential to Europe.

Vienna is geographically strategic as it lies in the center of the European commonwealth—a market of more than 460 million people. If Vienna contains a strong Christian influence, then that influence will spread as the city influences other regions of the continent.

Currently the spiritual climate of Vienna is changing so that people are exploring non-Catholic Christianity. It is an opportune time to initiate a church plant because of the heightened awareness toward spirituality.
