Desiring God has a good post on Church Planting and God’s sovereignty, related to Matthew 10. Here are a couple portions:
“Unreached nations like Afghanistan, Indonesia and Bangladesh represent some of the largest and fastest-growing population centers on earth. Yet fewer than five percent of cross-cultural workers serve among the challenging “nations, tribes, peoples and languages” scripture has promised will be worshiping around the throne in the New Heavens and New Earth (Revelation 7:9).
The pragmatic human response to this dynamic is to work harder, to pour more resources into the battle, to excoriate those who sit on their hands. But the reality is that, even if everyone gave to the point of poverty and obeyed to the point of death, the results would be fruitless apart from a sovereign work of the Spirit to draw the lost to the Father.
Our response to the plight of the unreached reveals the depth of our view of God. Do we truly believe it is the mission of God to reconcile the nations to himself? And, as counterintuitive as it may seem, do we believe that our proclamation of the gospel is the means that he has ordained to accomplish this? The Indonesian church planters I met are deeply aware of this truth—and it is what gives them faith when their efforts seem frail in the face of spiritual opposition.”
