When it comes do Disciple Now I do think you should dream big, but it never hurts to think small.  Think about the great movements of God.  The way the Gospel spread like wildfire in the early church, the First Great Awakening, many of the other great revivals.  What do they have in common? They started small.  they started with small groups of people praying together in small homes or rooms.  Then out of this, a great move of God exploded.  Think about what Disciple Now is.  It is a group of students meeting, studying and praying together in a small room.  Why couldn't that turn in to an amazing revival.  So when you are planning your Disciple Now and choosing your Disciple Now Curriculum, think small.  Make sure your Disciple Now Curriculum is conducive to a small group and that your Disciple Now Curriculum has the potential to be a spark for a great move of God.  Granted it takes more than a Disciple Now Curriculum, but a strong Disciple Now Curriculum is a great start.
