If world evangelization had depended on the Jewish church in Jerusalem it never would have materialized. Antioch became the missionary church. It was there the disciples were first called Christians. It was a church that turned outward. The church that is turned inside out is the church that will turn the world upside down.
Missions is an all-inclusive word.
To have a genuine burden for missions is to have a passion to save all who are in need, whether they be across the seas, across the state, or across the street. There are human needs in every community. There are homes and lives troubled with illness, poverty, problems such as divorce, drugs, and alcoholism. The outgoing church will minister to these in the spirit of Christ. Christ's love at the center is the true salvation of the church in difficulty.
