Here is a rich description of the mission which God calls us to as believers, expressed in the words of the Lausanne commitment at Cape Town, South Africa
This is section 10 of that commitment word for word. It is an exciting and joyous mission. How are you involved?
We love the mission of God
We are committed to world mission, because it is central to our understanding of God, the Bible, the Church, human history and the ultimate future. The whole Bible reveals the mission of God to bring all things in heaven and earth into unity under Christ, reconciling them through the blood of his cross. In fulfilling his mission, God will transform the creation broken by sin and evil into the new creation in which there is no more sin or curse. God will fulfil his promise to Abraham to bless all nations on the earth, through the gospel of Jesus, the Messiah, the seed of Abraham. God will transform the fractured world of nations that are scattered under the judgment of God into the new humanity that will be redeemed by the blood of Christ from every tribe, nation, people and language, and will be gathered to worship our God and Saviour. God will destroy the reign of death, corruption and violence when Christ returns to establish his eternal reign of life, justice and peace. Then God, Immanuel, will dwell with us, and the kingdom of the world will become the kingdom of our Lord and of his Christ and he shall reign for ever and ever.
A) Our participation in God’s mission. God calls his people to share his mission. The Church from all nations stands in continuity through the Messiah Jesus with God’s people in the Old Testament. With them we have been called through Abraham and commissioned to be a blessing and a light to the nations. With them, we are to be shaped and taught through the law and the prophets to be a community of holiness, compassion and justice in a world of sin and suffering. We have been redeemed through the cross and resurrection of Jesus Christ, and empowered by the Holy Spirit to bear witness to what God has done in Christ. The Church exists to worship and glorify God for all eternity and to participate in the transforming mission of God within history. Our mission is wholly derived from God’s mission, addresses the whole of God’s creation, and is grounded at its centre in the redeeming victory of the cross. This is the people to whom we belong, whose faith we confess and whose mission we share.
B) The integrity of our mission. The source of all our mission is what God has done in Christ for the redemption of the whole world, as revealed in the Bible. Our evangelistic task is to make that good news known to all nations. The context of all our mission is the world in which we live, the world of sin, suffering, injustice, and creational disorder, into which God sends us to love and serve for Christ’s sake. All our mission must therefore reflect the integration of evangelism and committed engagement in the world, both being ordered and driven by the whole biblical revelation of the gospel of God.
‘Evangelism itself is the proclamation of the historical, biblical Christ as Saviour and Lord, with a view to persuading people to come to him personally and so be reconciled to God…The results of evangelism include obedience to Christ, incorporation into his Church and responsible service in the world… We affirm that evangelism and socio-political involvement are both part of our Christian duty. For both are necessary expressions of our doctrines of God and humankind, our love for our neighbour and our obedience to Jesus Christ…The salvation we proclaim should be transforming us in the totality of our personal and social responsibilities. Faith without works is dead.’
‘Integral mission is the proclamation and demonstration of the gospel. It is not simply that evangelism and social involvement are to be done alongside each other. Rather, in integral mission our proclamation has social consequences as we call people to love and repentance in all areas of life. And our social involvement has evangelistic consequences as we bear witness to the transforming grace of Jesus Christ. If we ignore the world, we betray the Word of God which sends us out to serve the world. If we ignore the Word of God, we have nothing to bring to the world.’
We commit ourselves to the integral and dynamic exercise of all dimensions of mission to which God calls his Church.
God commands us to make known to all nations the truth of God’s revelation and the gospel of God’s saving grace through Jesus Christ, calling all people to repentance, faith, baptism and obedient discipleship.
God commands us to reflect his own character through compassionate care for the needy, and to demonstrate the values and the power of the kingdom of God in striving for justice and peace and in caring for God’s creation.
In response to God’s boundless love for us in Christ, and out of our overflowing love for him, we rededicate ourselves, with the help of the Holy Spirit, fully to obey all that God commands, with self-denying humility, joy and courage. We renew this covenant with the Lord – the Lord we love because he first loved us.
