Matthew 28:19-20, “Go therefore, and make disciples of all the nations, baptizing them in the name of the Father and the Son and the Holy Spirit, teaching them to observe all that I commanded you; and lo, I am with you always, even to the end of the age.”
This is the church’s great commission. This happens in local churches where discipleship occurs in the context of the diversity and unity of the body dynamic. To disciple nations, there must be churches to do that work.
