What does the Bible say about missions? It says that God intends to be worshiped by people from every nation, and that he sends his people to make that possible. This is not a single verse or a New Testament afterthought. It is a single arc that runs from Genesis to Revelation, and it gives the church its reason to go.
The word most often translated "nations" is the Greek ethne and the Hebrew goyim. It does not mean political countries. It means peoples, ethnic and language groups. When the Bible speaks of all nations, it is speaking of every distinct people on earth, and that meaning shapes everything that follows.
Where does missions begin in the Bible?
Missions begins with a promise to one man. In Genesis 12, God calls Abram out of his country and makes a promise that reaches far beyond him.
"I will bless those who bless you, and whoever curses you I will curse; and all peoples on earth will be blessed through you." (Genesis 12:3)
From the first chapters of Scripture, God's purpose is not one nation only but all peoples on earth. Abraham is chosen so that through his family the blessing of God would reach every family of the earth. The promise sets the trajectory for the rest of the Bible.
That trajectory continues through Israel's worship. The Psalms return again and again to the nations. Psalm 67 asks God to bless his people so that his way may be known on earth and his salvation among all nations. Psalm 96 calls the singer to declare God's glory among the nations and his marvelous deeds among all peoples. Israel was never meant to keep the knowledge of God to itself.
Is missions only in the New Testament?
No. The concern for the nations is woven through the Old Testament, not added later. The prophet Isaiah records God speaking to his servant and widening the servant's task beyond Israel.
In Isaiah 49:6 God says it is too small a thing for the servant only to restore Israel; he will also make him a light for the nations, that God's salvation may reach to the end of the earth. The reach of salvation to the ends of the earth is an Old Testament vision before it is a New Testament command. The New Testament does not introduce missions. It carries forward what God had promised and announced all along.
What did Jesus say about missions?
Jesus gathered the whole of it into a commission. After his resurrection he told his disciples that all authority in heaven and on earth had been given to him, and on that basis he sent them out.
- Matthew 28:18-20 — go and make disciples of all nations, baptizing and teaching them to obey everything he commanded.
- Acts 1:8 — the disciples would receive power from the Holy Spirit and be his witnesses in Jerusalem, in all Judea and Samaria, and to the ends of the earth.
These are not two separate assignments. The Great Commission gives the church its task, and Acts 1:8 gives it the pattern: witness that moves outward, from home to the farthest peoples. The command rests on Christ's authority, so missions is obedience rather than ambition. You can read more in our companion piece, what is the Great Commission.
What is the goal of missions in the Bible?
The goal is worship. The Bible does not present missions as an end in itself but as the means by which God gathers worshipers from every people. John sees the finished work in Revelation 7:9: a great multitude that no one could count, from every nation, tribe, people and language, standing before the throne of God.
That scene is the answer to the promise made to Abraham. What God pledged in Genesis 12 he completes in Revelation 7. The blessing that began with one family reaches every family, and the nations that were called are finally gathered in praise. Missions exists to close that gap between the promise and its fulfillment.
Which Bible verses speak most directly about missions?
A few passages carry the arc especially clearly:
- Genesis 12:1-3 — all peoples on earth blessed through Abraham.
- Psalm 67 and Psalm 96 — God's glory and salvation declared among all nations.
- Isaiah 49:6 — the servant as a light for the nations, salvation to the end of the earth.
- Matthew 28:18-20 — the command to make disciples of all nations.
- Acts 1:8 — witness to the ends of the earth.
- Revelation 7:9 — worshipers from every nation, tribe, people and language.
Read together, these verses show why missions cannot be optional for the church. It is the shape of God's purpose in history.
What does this mean for unreached peoples today?
If "nations" means peoples rather than countries, then the task is measured in peoples, not borders. By some estimates there are still around 7,400 people groups considered unreached, together numbering roughly 3.4 billion people with little or no access to the gospel. Those figures are estimates and definitions vary, but the scale is not in doubt. Many peoples remain who have not yet heard.
This is where the biblical arc meets present work. The Ends of the Earth Initiative exists to help close that gap by training and supporting national pastors who live near unreached peoples, with partners in Thailand and India. You can read more about that calling on our vision page. Giving is launching soon, and our 501(c)(3) status is pending; if you would like to help send and support these workers, you can partner with us as that opens.
The question is not really whether missions is biblical. Scripture answers that from Genesis to Revelation. The question is whether we will take our place in the story God is already telling among the nations.
