What is missions?

Question 11021

Missions is not a department of the church’s work. It is the heartbeat of what the church exists to do. From the call of Abraham in Genesis 12 to the vision of every tribe and tongue gathered before the throne in Revelation 7, the Bible tells the story of a God who pursues the nations with saving purpose. Understanding missions biblically means grasping that this is not an optional activity for the especially passionate but the defining reason the church remains on earth.

The Biblical Foundation

God’s missionary heart is visible from the beginning. His promise to Abraham was not a private blessing: “In you all the families of the earth shall be blessed” (Genesis 12:3). Israel was chosen not for her own sake alone but as a vehicle through which God’s blessing would reach the nations. The Psalms repeatedly call on the nations to worship the LORD (Psalm 67:3-4; 96:3). The prophets envisaged a day when “the earth shall be full of the knowledge of the LORD as the waters cover the sea” (Isaiah 11:9). The missionary impulse did not begin in the New Testament. It runs through the entire biblical story as one of its central themes.

In the New Testament, Jesus made the scope explicit. “You will be my witnesses in Jerusalem and in all Judea and Samaria, and to the end of the earth” (Acts 1:8). The book of Acts records the fulfilment of this promise as the gospel moved outward from Jerusalem through the Roman world, carried by apostles, missionaries, and ordinary believers alike. Paul understood himself as an apostle to the Gentiles (Romans 11:13), and his missionary journeys established churches across Asia Minor, Macedonia, and Greece in a single generation.

What Missions Is

At its core, missions is the church’s obedient response to God’s command to take the gospel to all peoples. It involves crossing boundaries, whether geographical, cultural, linguistic, or ethnic, to proclaim Christ where He is not yet known. The word “missions” (from the Latin missio, meaning “sending”) reflects the sending nature of God Himself. The Father sent the Son. The Son sent the Spirit. The Spirit sends the church. Missions is participation in the sending activity of the triune God.

This includes evangelism (the proclamation of the gospel to those who have not heard it), church planting (the establishment of local congregations of believers in new contexts), and the teaching and training of new believers and leaders so that the church can sustain itself and grow. Missions is not humanitarian work, though compassion and practical service often accompany it. The defining characteristic is the communication of the gospel with the intention that people will come to saving faith in Jesus and be gathered into local churches.

The Local Church and Missions

The New Testament pattern is that missionaries are sent from and accountable to local churches. The church at Antioch, under the Spirit’s direction, set apart Paul and Barnabas and sent them out (Acts 13:1-3). Paul regularly reported back to the churches that had commissioned him (Acts 14:26-27). Mission agencies serve a valuable function in coordinating and supporting cross-cultural work, but they do not replace the local church as the sending authority. The church sends; the agency facilitates. Where this order is reversed, both mission and church are weakened.

Supporting missions is not restricted to sending missionaries. Prayer is the engine of missionary work, and Paul requested it constantly (Ephesians 6:19-20; Colossians 4:3-4; 2 Thessalonians 3:1). Financial support is a genuine partnership in the gospel (Philippians 4:15-17). Hospitality, encouragement, and practical care for missionaries and their families are all forms of missionary participation that every local church can engage in.

So, now what?

Missions exists because God loves the nations and has commissioned His church to reach them. Every local church should be engaged in missionary work, whether through sending, supporting, praying, or giving. The task remains unfinished. Billions of people have never heard the name of Jesus in a way they can understand. The urgency of the Great Commission has not diminished with the passing of two thousand years. It has intensified.
