"How is the church prophetic as well as evangelistic? The church fulfills its prophetic calling in at least the following four ways:
1. The church is
prophetic when it creates and sustains a reconciled and reconciling
community of believers (2 Cor 5:16-21; Eph 2; Phil 2:1-11; Col
1:21-23). When this happens, evangelism takes on prophetic dimensions.
Reconciliation with God is demonstrated by genuine reconciliation within
the Christian community and by a continuing ministry of healing
reconciliation in the world.
2. The church is
prophetic when it recognizes and identifies the true enemy (Mt 10:28;
Lk 12:4-5; Rom 8:38-39; 1 Cor 15:26; eph 6:12; Rev 12:9; 20:2, 14).
Satan's trick is to point to false enemies and pose false alternatives.
... the true enemy of humankind is Satan and the 'principalities' and
'powers' under his control (Eph 6:12).
3. The church is
prophetic when it renounces the world's definition and practice of power (Mt
20:20-28; 23:1-12; Mk 9:35-37; Lk 9:46-48; 22:24-27; Jn 13:12-17; 1 Cor
1:18-31; Phil 2:1-11). Jesus talked about power, but he insisted that his
followers see and use power differently from the way the world does. ...
4. The church is prophetic when it works for justice in society (Ps 82:1-4; Amos 5:21-24; Mt 11:4-6; Lk 3:10-14; 4:18-21; Eph 5:11). Christians bear a particular responsibility to the poor and oppressed. God's people are called to defend the cause of the poor and needy within each nation and world wide. The treatment of the poor, the needy and 'those who have no social power' becomes a test of the justness of any society or political system. When the church works on behalf of the poor, it is meeting specific human need and is making a politically significant contribution, practicing 'the politics of Jesus.'
The prophetic and evangelistic dimensions of the gospel are totally interwoven in the life and witness of the community of the king, as they were in Jesus' own life."
