It would be simplistic, and biblically wrong, to say that each believer is only responsible for their own little corner of the world. The call to be a follower of Jesus Christ starts with the transformation of a single heart; but is as broad as the call to transform the whole world.
In Romans chapter 10, Paul challenges believers to remember that part of the Christian life involves outreach as well as personal transformation. “How then will they call on Him in whom they have not believed? How will they believe in Him whom they have not heard? And how will they hear without a preacher?” (Romans 10:14).
We, as a church, are called to have the same concern for people, both at home and abroad. People are the same, regardless of where they live. People without Christ are frustrated, bewildered, and defeated by life’s problems. They long for what Christ offers; fulfillment, strength, peace, wisdom, hope, meaning, and life eternal. It is our joy as a people of God, to point the way to Christ, where all these desires can be satisfied.
