1.The Command of the Risen King
The last words a man speaks carry weight, and the last command of the risen Lord Jesus to His church was clear and deliberate: “Go therefore and make disciples of all the nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all things that I have commanded you” (Matthew 28:19–20). He said the same in other words on other days — “Go into all the world and preach the gospel to every creature,” and “you shall be witnesses to Me… to the end of the earth.”
This is not a gentle suggestion for the eager few, nor a special project for one enthusiastic era of the church. It is the standing order of the King, binding upon His whole church in every generation until He comes again. John Harris, expounding this “Great Commission,” pressed upon the church of his day that the evangelization of the world is not an optional extra, to be taken up once the more important business is done, but its plain and urgent duty — the very reason it is left in the world at all. A church that forgets this has forgotten what it is for.
And mark the word on which the whole command turns: “Go therefore.” It rests on what comes just before it — “All authority has been given to Me in heaven and on earth.” The church is not sent out on its own errand, hoping for the best against long odds; it is sent by the One to whom all power belongs, the risen King of the universe. That is why the task, for all its size, is not presumptuous but obedient, and not hopeless but sure. We go under orders, and under the authority of the One who gave them.
2.For All the World
Notice the sweep of the command: all the nations, every people, every language, every kind of sinner under heaven. The gospel knows no boundary of race or class or respectability. It is for the great city and the far village, for the religious and the openly wicked, for the near neighbor and the most distant tribe, for the powerful and the forgotten alike.
No one is beyond its reach, and no one is shut out from its offer; the invitation of Christ goes out freely to whoever will come. This is a rebuke to every narrowness in us — every temptation to think some person too hard, too foreign, or too far gone to be worth the telling. If God so loved the world, His people dare not love only their corner of it. This universal scope is part of what makes the task so vast — and part of what makes it so glorious.
This sweep reaches all the way down to the reader’s own street. The “nations” are not only far-off lands requiring a passport; they are also the people God has set around each of us — in the village and the city, the family and the workplace, the poor barrio and the crowded market. A believer need not cross an ocean to obey the Commission; he begins where he stands, with the neighbor at hand, even as the church together reaches for the ends of the earth. The far field and the near one are both part of the one harvest.
3.Because Souls Are Lost
Why does this command press so hard upon the conscience? Because of what is true of people apart from Christ. Scripture will not let us pretend that all is well with the world, or that the many roads of men all quietly arrive at the same God in the end. Those without the Savior are lost — under the guilt of sin, subject to a coming judgment, “having no hope and without God in the world” (Ephesians 2:12).
If the gospel is true, then the eternal welfare of every soul hangs upon whether it hears and believes; and men cannot believe in One of whom they have not heard, nor hear without someone to tell them. This is the sobering reason evangelism can never be a mere hobby for those who happen to enjoy that sort of thing: real people, whom God loves, are perishing, and the one word that can save them has been entrusted to us. To keep silent is not neutral; it is to withhold bread from the starving.
This truth is meant to sober us, not to sink us into despair. The lostness of the world is real, but so is the power of the gospel to save all who believe it; the message we carry is not a frail hope but “the power of God to salvation for everyone who believes” (Romans 1:16). So we speak with urgency, because the need is real and the time is short — but also with confidence, because the word we bring is exactly the word that raises the dead. Urgency without despair, and confidence without ease: that is the spirit of true evangelism.
4.Because We Love
Yet the fear of judgment alone will not sustain the work for long; the deepest and most enduring motive is love. We evangelize because we love God — whose glory is bound up in the salvation of sinners, and who has plainly commanded us to go — and because we love people, who are dear to Him and dying without Him. Duty by itself soon grows cold and mechanical, a heavy task done with a sigh; but evangelism born of a heart warmed by the love of Christ endures through discouragement, weariness, and hardship.
As Paul confessed, “the love of Christ constrains us” (2 Corinthians 5:14) — it presses, compels, leaves us no rest. When we have truly felt how we ourselves were sought when we were far off, and saved when we deserved the opposite, we cannot easily leave others in the dark. The love that found us will not sit still in us; it reaches, of its own nature, toward those who have not yet been found.
Love is also what carries a witness through rejection, which will surely come. Not every hearer will believe; some will scoff, some will turn away, some will grow cold toward the one who told them. Duty alone will quit under that discouragement, but love does not keep score of its rebuffs. It remembers how patient God was with us, and how many times He sought us before we yielded, and so it keeps loving and keeps speaking — leaving the results, as it must, in the hands of the Lord of the harvest.
5.The Work of Every Believer
Here a great and common mistake must be corrected. The Commission was not handed to a special class of clergy or professional missionaries while the rest of the church looked on and paid the bills. It was given to the whole people of God. Every believer is a witness — “you shall be witnesses to Me” — called to make Christ known in the place where God has set him, by the life he lives and the word he speaks.
The proof is written into the story of the early church. When persecution scattered the believers from Jerusalem, we are told that it was not the apostles — they stayed — but the ordinary, unnamed Christians who “went everywhere preaching the word” (Acts 8:4). So the humblest layman, the busy mother, the young convert, the pastor of a tiny flock — each has a real share in this task, and each may be the very means by which some soul first hears of the Savior. The question is not whether you are called to witness, but only where, and to whom.
And witnessing is rarely a matter of grand eloquence. Most often it is the quiet weight of a changed life, joined to a simple, honest word: this is what Christ has done for me, and He will receive you too. The blind man whom Jesus healed silenced his learned accusers with a testimony no one could refute — “one thing I know: that though I was blind, now I see” (John 9:25). That kind of witness lies within the reach of every believer, however plain, for no one can argue a man out of what God has plainly done in him.
6.To the Work — and He Goes With Us
D. L. Moody titled one of his books with a ringing summons — To the Work! The fields are white for harvest, he urged; the time is short; the laborers are few; and the call of Christ is to begin now, not someday when it is more convenient. The harvest will not wait for us, and neither should we wait upon it.
Yet the command comes wrapped in a promise that takes away all fear: “Lo, I am with you always, even to the end of the age” (Matthew 28:20). We do not go out in our own strength, nor alone. The same Lord who sends us goes with us, and works through our weak and stumbling words by His Spirit, so that the increase never finally depends on our eloquence but on Him. So we take up the task not as a crushing burden laid on unwilling shoulders, but as the highest privilege a mortal can be given — to be, in the hands of God, the bearer of good news to the perishing.
And because the increase is God’s and not ours, the work is watered above all by prayer. Jesus, seeing the great harvest and the few laborers, did not first tell His disciples to organize; He told them to “pray the Lord of the harvest to send out laborers into His harvest” (Matthew 9:38). So we go, but we also pray — for open doors, for open hearts, for boldness in our own timid mouths, and for the Spirit to do what no argument of ours ever could. The one who both prays and goes will not labor in vain.
Here, then, is the whole of it: a clear command from a King with all authority, a world of real people who are lost, a love that will not let us rest, a task laid upon every believer, and a Lord who goes with us and works through us. What remains is not to be further persuaded, but simply to obey — to go, in His strength, and tell.
