Public Missiology: How Local Churches Witness to a Complex World

8 Jan 2024 Online

The Lausanne Leadership Development Network hosted a webinar with Dr Gregg A. Okesson, Provost and Senior Vice President of Academic Affairs at Asbury Seminary in Kentucky. It is based around the themes mentioned in his book: Public Missiology: How Local Churches Witness to a Complex World, with space for questions and comments.

Dr Okesson is an engaging and Holy Spirit– led speaker on the topic of public missiology. Drawing from both academic research as well as practical insights from international experience, the webinar will seek to define public leadership, public witness, what constitutes ‘thick’ public story and ‘thick’ witness and how to continue to lead in the complex context we find ourselves in.
