The Great Commission is our Lord's idea, and only He in His sovereignty and omniscience knows when and how it will be fulfilled. However, since He gave us the command and has promised to equip us to do His will, we must assume that He intends us to fulfill the Great Commission in each generation.

M Today every nation in the world is receiving the gospel either through trained disciples, radio, television or literature. But even though there is a witness for Christ in every nation, the Great Commission is not fulfilled, and it will remain unfulfilled until there are sufficient numbers of disciples in every nation to saturate their country, and all the diverse ethnic and people groupings in it, with the gospel. We must become as interested in making disciples as we are in conversions, more interested in spiritual multiplication than we are in spiritual addition. Fulfilling the Great Commission does not mean that every person will respond to the gospel in our generation. But it does mean that we should seek to make a prayerful, intelligent, aggressive presentation of the gospel to every living person and leave the results to God.
