Could the psalm writer have looked across the years to see the gospel go throughout the earth? This psalm surely speaks of the fulfillment of the great commission (Mat_28:18-20), when Jesus commanded that the gospel be taken to all nations. Count yourself among that great crowd of believers worldwide who know the Savior; praise him for his Good News; and share that gospel so that the harvest will be abundant.
Psalms 67:7
