How can we establish the link between good governance and the restoration of peace? How can good governance contribute to the restoration of peace in DR Congo? Behind these questions lies a vision of good governance that appeals to ethical requirements in order to put out of harm's way any desire to gain power by force. The approach to the concept of governance is theological and ethical. How does this approach differ from that of jurists, political scientists and political scientists? In this work, the author shows that good governance is possible if it is exercised in diaconal forms, taking the model of Joseph in Egypt (Gn41,38-57) and the model of Jesus in the Gospel of John (Jn10,1-18). In doing so, for C. Ali Mwamba, good governance implies peace.
