The church’s mission to make disciples of all nations is an insurmountable task—apart from the sovereignty of God. Thankfully, Paul assures us that God intends to save his elect and will do so through the faithful proclamation of the gospel by faithful preachers of the gospel.
For “everyone who calls on the name of the Lord will be saved.”
How then will they call on him in whom they have not believed? And how are they to believe in him of whom they have never heard? And how are they to hear without someone preaching? And how are they to preach unless they are sent? As it is written, “How beautiful are the feet of those who preach the good news!”
