There is enough evangelistic activity to reach the whole world.
Enough activity for every one in the world to hear a 1-hour presentation of the Gospel every other day all year long.
Over 1,43 billion hours of evangelism generated by Christians every year: personal witness, radio, TV, Internet, literature, etc.
But this evangelistic activity is unevenly targeted:
91% of all Christian outreach/evangelism does not target non-Christians, but targets other Christians.
