The Church is called and commissioned by Christ and empowered with the Holy Spirit to bear WITNESS for Christ and His saving Gospel to all the nations of the world (Matt 28:18-20; Mark 16:15-18; Luke 24:46-49; Act 1:8). This is a delicate and complex task. This missionary WITNESS for Christ involves:
incarnational CONTEXTUALISATION (or INCULTURATION),
compassionate SERVICE, and
– that all may believe that Christ has come as the Divine Son, to save this sinfully lost and perishing world so they would have eternal life and experience the refreshing of the Holy Spirit and liberation of the sons of God.
What the Church does in holiness and love among the members is her COMMUNION with one another and in Christ (1John 1:3, 7). What the Church does in holiness and love towards the world is her MISSION for Christ and like Christ (John 20:21). This CHURCH’S MISSION (witness and good works) to the world involves:
firstly EVANGELISATION through the PREACHING of Christ’s saving Gospel to the unsaved to become disciples of Christ;
secondly MINISTRATION through compassionate SERVICE to the society as the “merciful” and the “peacemakers”; and
thirdly CHRISTIANISATION through righteous and responsible ACTION as “light and salt” for justice and order in the society.
To effectively sustain the Church’s Communion and Mission, it is necessary that Disciplers and Word Ministers of the Church labour to PERFECT OR TRAIN THE SAINTS by edifying them with the equipment of God’s Word which will enable the saints do the work of the ministry properly (Eph 4:11-14; 2Tim 2:2; 3:14-17).
