Here are some helpful posts for small-town pastors:

Don’t Measure Small-Town Ministry Simply by Its Size – Stephen Witmer (TGC)
My friends’ ministry is expressing something of God and his gospel that couldn’t be expressed through a massive revival. All their many sacrifices, their unconditional friendship to a young Muslim family still blind to the glory of Christ, their consistent, prayerful sharing of the gospel with those who will listen—these demonstrate a generous God and a lavish gospel.

No City Is Too Small for God: Reaching the Crevices of the World – Josh Manley (DG)
But if you labor in relative obscurity and are tempted to think your work is unstrategic, I want to encourage you that, if you labor for the Lord, there is no such thing as an unstrategic city. He cares about every last sheep.

Brothers, Preach Your Heart Out — No Matter How Few People Are in the Room – Tim Counts (IX)
The Kingdom of God is like a mustard seed. Only the Lord knows what he will do with an army of preachers committed to expositing God’s Word with precision and passion week in and week out in small churches across America.

Brothers, let’s press on for the sake of the kingdom!
