First of all, as everyone knows, God’s mission flows from God to Christ to the Holy Spirit, who empowers the church, who carries on the mission to the world. In the mission of the church individual, Christians embody God’s mission and are empowered by the Holy Spirit to convey it to the world.
Secondly, the church just to be a place where people can get together to pray and fellowship. Also, it is a group of people called out of this society by God in order to accomplish purpose which is just for giving encouragement to the church members, providing social activities and personal salvation.
Specifically, Jesus built the church (Matthew 16:18), he is the head of the church (Ephesians 1:22; 4: 15). So, Jesus gave us this marching order “Go” therefore and make disciples of all nations, baptizing them in the name of the Father and the Son and the Holy Spirit. Teaching them to observe all things that I have commanded you, and I am with you always, even to the end of the time or age (Matthew 28:19-20). In addition, Jesus gave us a job of preaching the gospel of the kingdom of God to the whole world (Mark 16:15; Matthew 24:14).
Finally, this also our mission which is to increase more people in the kingdom of God.
