Matthew 28:19-20 New International Version (NIV)
19 Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit,
20 and teaching them to obey everything I have commanded you. And surely I am with you always, to the very end of the age.”
Discipleship is not one of the things the church is supposed to do.
It is THE thing the church is commanded to do.
“The mark of a great church is not its seating capacity, but its sending capacity.”
