I highly recommend the following videos that teach discipleship and multiplication concepts gleaned from Scripture and the experience of Curtis Sergeant, a seasoned church-planter:
Though the presentation (and presenter) are not flashy at all, these concepts are literally saturating the mission field and seeing some undeniable fruit. And, for all of us Americans, they are starting to take hold of the U.S. in some profound ways (I think of “bigger” names like Francis Chan, David Platt, people from the Passion Conference, etc. who are teaching and preaching very similarly).
Gives me a lot of hope and vision for passing on Christ in power to the current and future generations.
