The concept of the "Completion of the Mission" in the Christian faith primarily refers to the fulfillment of the Great Commission, as given by Jesus Christ to His disciples. This mission is rooted in the directive to spread the Gospel and make disciples of all nations, as recorded in the New Testament.

Biblical Foundation

The Great Commission is explicitly stated in Matthew 28:18-20 : "Then Jesus came to them and said, 'All authority in heaven and on earth has been given to Me. Therefore go and make disciples of all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Spirit, and teaching them to obey all that I have commanded you. And surely I am with you always, to the very end of the age.'"

This passage underscores the authority of Christ, the scope of the mission (all nations), the method (baptizing and teaching), and the promise of His presence.

The Apostolic Example

The early church, as depicted in the Acts of the Apostles, provides a model for the completion of this mission. Acts 1:8 records Jesus' words before His ascension: "But you will receive power when the Holy Spirit comes upon you, and you will be My witnesses in Jerusalem, and in all Judea and Samaria, and to the ends of the earth."

The apostles, empowered by the Holy Spirit, began their mission in Jerusalem and expanded outward, as seen in the missionary journeys of Paul and the spread of the Gospel throughout the Roman Empire. The Book of Acts chronicles this expansion, highlighting the role of the Holy Spirit in guiding and empowering the early church.

Theological Implications

The completion of the mission is not merely a historical task but a continuing mandate for the church. It reflects the heart of God for the redemption of humanity and the establishment of His kingdom on earth. The mission is both evangelistic and transformative, calling for the conversion of individuals and the discipling of nations.

Romans 10:14-15 emphasizes the necessity of preaching for the mission's completion: "How then can they call on the One in whom they have not believed? And how can they believe in the One of whom they have not heard? And how can they hear without someone to preach? And how can they preach unless they are sent? As it is written: 'How beautiful are the feet of those who bring good news!'"

Eschatological Perspective

The completion of the mission is also tied to eschatological expectations. Jesus, in Matthew 24:14 , states, "And this gospel of the kingdom will be preached in all the world as a testimony to all nations, and then the end will come." This suggests that the fulfillment of the Great Commission is a precursor to the return of Christ and the consummation of the age.

Contemporary Application

In contemporary Christianity, the mission continues through various means, including evangelism, church planting, and social justice initiatives. The global church is called to engage with diverse cultures and contexts, utilizing modern technology and communication to reach unreached people groups.

The mission's completion is seen as a collaborative effort, involving prayer, financial support, and active participation in mission work. The church is encouraged to remain faithful to the original commission, adapting methods while maintaining the integrity of the Gospel message.

Challenges and Encouragement

The task of completing the mission faces numerous challenges, including persecution, cultural barriers, and theological disputes. However, believers are encouraged by the promise of Christ's presence and the power of the Holy Spirit. The mission is ultimately God's work, and He is faithful to accomplish His purposes through His people.
