Thought I’d let you all know about Leader Formation International, a ministry headed up by Bill Lawrence, Senior Professor Emeritus of Pastoral Ministries and Adjunct Professor of Doctor of Ministry Studies at Dallas Theological Seminary. Looks like he has some great resources on discipleship and leadership.
Also, if you are a pastor, I’d highly recommend his book Effective Pastoring. Unfortuantely, I was unable to take any of his classes during seminary, but I’ve heard nothing but great things about him. His book has excellent insights for shepherding a congregation.
