Consider these who left home to proclaim the gospel to those who have never heard:
- David Livingston left Scotland and went to Africa before everyone in Scotland had become a Christian.
- William Carey left England and went to India before everyone in England had become a Christian.
- Adoniram Judson left America and went to Burma before everyone in America had become a Christian.
Consider Jesus' instructions in Acts 1:8; "But you will receive power when the Holy Spirit has come upon you, and you will be my witnesses in Jerusalem and (in union with or even also) all Judea, Samaria, and to the end of the earth." Our task of reaching the unreached who have never heard is not independent of the field at home, but the fields that have never heard must be our priority.
