“… ‘everyone who calls on the name of the Lord will be saved.’
But how are they to 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?
…So faith comes from hearing, and hearing through the word of Christ.”
Romans 10:14-15, 17
