Peter Cheyne occasionally publishes a newsletter looking at some theme related to making disciples. A new one is available and the theme is “Not Ashamed of the Gospel”.
You can get it (and older ones) from https://app.box.com/s/mvrfjqk4bd2yhn2uqnr8.
If you want notification of future newsletters, go to the Followers facebook page and “like” it. Then choose whether to receive posts on your newsfeed or to receive notifications.
For lots more resources about disciple-making are available at www.followers.org.nz.
