Evangelism and diakonia belong together in the perspective of the Great Commission. Evangelism is sharing one’s faith and conviction with other people and inviting them to discipleship. Diakonia is the gospel and our faith in action and is expressed through loving our neighbor. Evangelism and diakonia are like the two blades on a pair of scissors. They give the church identity and they are functions of the church. This is not just a matter of doing evangelism and diakonia in balance and alongside each other. Rather, evangelism and proclamation have social and diaconal consequences as we call people to discipleship and to be salt and light in all areas of life. And diakonia and social involvement have evangelistic consequences as we demonstrate faith in action and witness to transformation. This ecumenical volume brings together these perspectives on integral mission.
