1. God's Heart for All Nations
Before we speak of the church's duty, we must see God's own purpose, for missions begins not with us but in the heart of God. From the very start He set out to bless not one nation only but "all the families of the earth," as He promised to Abraham; the covenant that founded a single people was, from the first word, aimed at every people. Through the Psalms and the Prophets runs the same great hope — the day when all nations shall come and worship before the LORD, when His salvation shall reach "to the ends of the earth." This was never a hope Israel was meant to hoard; it was a light they were meant to carry.
And the Bible closes with the vision that shows where all history is going: a countless multitude "from every nation, tribe, people, and tongue," standing before the throne of God and of the Lamb. In this sense the whole of Scripture is a missionary book, the long story of God gathering to Himself a people out of every people on the earth — from the promise to Abraham, through the psalmists' longing and the prophets' visions, to the throne surrounded by the redeemed of all mankind. Missions, then, is not our idea imposed on a reluctant God, nor a cause we invented and asked Him to bless. It is God's own eternal purpose, older than the church and wider than any nation, and He calls us into it. To love missions is simply to love what God has always loved.
2. The Great Commission to the World
It is on this foundation that the risen Christ gave His command: "Go therefore and make disciples of all the nations." Notice that one word — all the nations. The Commission is not satisfied by our carrying the gospel only to those near at hand, in our own town and our own tongue, comfortable among people like ourselves; it reaches, by Christ's own word, to every people group on the face of the earth. He told His disciples they would be His witnesses in Jerusalem, in Judea and Samaria, and "to the end of the earth" — nearer and farther together, the familiar and the distant, none left out.
This means the church's task is not yet complete while any people remains unreached. Until the gospel has actually gone to the last tribe and tongue that has never heard it, the Commission still stands open, still unfinished, still binding. It will not do to say the work is done because it is done in our own country; the Lord's word was "all the nations," and His reckoning takes in peoples we have never seen. The Commission is global by the plain command of the Lord who gave it, and it remains the marching order of the church until He comes. Every generation of believers stands under the same word, and none may quietly set it aside as finished.
3. Carey and the Awakening of the Church
For long centuries much of the church grew strangely cold to this duty. Some even argued — with a straight face and an open Bible — that the Great Commission had been given only to the first apostles and had no claim on Christians now; that if God meant to save the nations, He would do it without human help. Under such teaching the churches settled comfortably at home, and the millions who had never heard were left to their darkness. It was a strange forgetting, and it lasted a long time.
Into this sleep came a poor English shoemaker and pastor, William Carey, who could not shake off the plight of the millions who had never once heard the name of Christ. In 1792 he published a small book with a long title — An Enquiry into the Obligations of Christians to Use Means for the Conversion of the Heathens — in which he argued, patiently and from Scripture, that the command to disciple all nations still binds the church, and that believers are therefore obligated to use means: to organize, to give, to send, and to go, rather than wait for God to act apart from them. Preaching to his fellow ministers on the text of Isaiah, he pressed the ringing charge that has stirred the church ever since: "Expect great things from God; attempt great things for God." That little book and that great faith helped to awaken the modern missionary movement out of its long slumber; and Carey did not merely write — he went, sailing to India as one of the first laborers of the movement he had roused. He is a standing rebuke to every excuse, and a standing encouragement to every ordinary believer who feels he has little to offer.
4. An Obligation, Not an Option
Carey's argument still stands, and it presses upon us with the same force. If the command of Christ still holds — and it does — and if to this day great multitudes have never once heard the name of Jesus — and they have not — then missions can never be a mere hobby for those few who happen to find it interesting, a special enthusiasm for the spiritually adventurous while the rest of the church looks on. It is a solemn obligation resting on the whole people of God, as binding as any other command of our Lord.
The apostle Paul felt it exactly so — not as an interest but as a debt. "I am a debtor," he said, to Greeks and to barbarians, to the wise and to the foolish — owing them the gospel he had himself received, as a man owes a message entrusted to him for another. He did not view the nations as an opportunity he might take up if it suited him, but as creditors to whom he owed what he carried. And what was true for Paul is true, in measure, for us. To keep the good news comfortably to ourselves while whole nations perish for lack of it is not a small oversight or a minor failing; it is a failure of both love and obedience at once. We hold in our hands the one message on earth that can save them, freely given to us and freely to be given; and we are charged, by the love of Christ and the command of Christ, to get it to them.
5. Every Land Reached by Its Own
How is this vast mandate to be carried out? Not by foreign missionaries alone, crossing seas to distant lands — vital and honorable as that work is, and always will be. It is carried out also, and increasingly, by raising up believers and churches within every nation who will reach their own people, in their own tongue, among their own neighbors, where they already live and are already understood. A local believer often has doors open to him that no foreigner could ever enter, and speaks with an accent of the heart that needs no translation.
The aim of missions, then, is not to plant a permanent dependence on outsiders, but to see the gospel take deep root in every land through its own sons and daughters, until each people has a living church of its own that carries the good news onward without help from abroad. This is a truth of great hope, and it is especially fitting for the church among peoples of modest means. You do not need great wealth, or foreign training, or a passport and an ocean voyage, to be part of the mandate; the ordinary believer, trained and sent among his own, is one of God's chosen instruments for reaching the nations. The pastor who equips the humble members of his own congregation to carry Christ to their families and neighbors is doing missionary work of the highest order, and helping to fulfill the very command of the Lord.
6. Toward a Certain Harvest
Finally, take courage: this mandate does not send us out toward an uncertain result, hoping against hope that our labor might come to something. The One who commands us also promised, in the same breath as the command, "Lo, I am with you always, even to the end of the age" — so that we never go alone, never labor by our own strength, never face the nations without the presence of the One who sends us. The command and the promise were given together, and neither may be taken without the other.
And the end is already sure. That great multitude from every nation and tribe and people and tongue is not a distant possibility that may or may not come to pass, depending on our success or failure; it is shown to us in the Revelation of Jesus Christ as an accomplished fact, a scene already certain in the counsels of God. Christ will have His people out of every people on the earth; not one for whom He died will finally be lost. We labor, then, not in the anxious hope that God's purpose might somehow succeed if we try hard enough, but in the settled certainty that it cannot fail — and we are given the honor of sharing in a work whose outcome is already guaranteed. There is no more hopeful labor under heaven than this: to spend ourselves for a harvest God has promised, and cannot fail to gather.
Let this settle the matter for us, then. The call to reach the nations is not a special burden laid on a heroic few, but the shared honor and duty of the whole people of God, resting on the plain command of Christ and the plain need of a perishing world. You need not wait for a call to some distant land to have a part in it; the neighbor who has never truly heard, the family member still in darkness, the village down the road with no witness — these are the nations too, and reaching them is the same great work. Whether God sends you far or keeps you near, give yourself without reserve to the purpose He has cherished since He first spoke to Abraham: a people for His name out of every people on earth. That purpose cannot fail, and you are invited to share in it.
7. Taking It to Heart
For reflection. Have you thought of world missions as God's own purpose, running through the whole Bible — or as an optional cause for those who happen to like it? What is your own share in the mandate: to go, to send, to give, to pray, or to help raise up laborers among your own people? And how does it change your labor to know the harvest from every nation is not a hope but a certainty?
