“Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit.” (Matthew 28:19)

We are commanded by Jesus to go and make disciples. So, what’s a disciple?

According to the Merriam Dictionary, a disciple is “one who accepts and assists in spreading the doctrines of another.”

Therefore, a disciple of Jesus is someone who is taught the gospel, accepts this knowledge, and is willing and able to teach the gospel to others. He is a pupil, a student, a follower of Christ. This is the goal of missions and our goal—to make followers of Christ. As the face of missions has changed over the past century, WIM has adapted its methods to be relevant to a vastly different world. Yet, the mission of making disciples remains the same.

Whether it be preaching, teaching, friendship evangelism, business as mission, or compassion ministry, WIM missionaries are working with three goals in mind:

EVANGELIZING the lost with the gospel of Jesus Christ
ESTABLISHING indigenous churches where there were previously none
EQUIPPING and serving leaders

How do you get started? What’s the process? These are great questions.

What is the 10/40 Window? (Infographic)

What is the 10/40 window? Why is this part of the world so important? Below is an explanation of the 10/40 window with some sobering statistics to follow. We are instructed by Jesus to pray to the Lord of the harvest for more workers. This is an area of the world that needs an army of workers!

The term 10/40 window became popular in the early ‘90s as a way to describe the least reached part of the world. With more than 67% of the world’s population living in this region and most of the least evangelized countries and people groups of the world in this region, it should get our attention! There is a huge need for willing, tenacious, and tough gospel workers.  

In simple terms, it is the area of the world between 10 and 40 degrees north latitude in the eastern hemisphere — a rectangular box that encompasses parts of Northern Africa, the Middle East and Asia. This is less than one-third of the world’s land mass, yet two-thirds (two-thirds!) of the global population lives within this area. Not only is this window heavily populated, but it is also characterized by extreme poverty and the highest concentration of people groups without access to the good news due to both resistance and lack of opportunities to reach them.

The following are some statistics from this region of the world that provide an idea of the scope of the task:

Goer or Sender? Find Your Role in God’s Plan

Article posted with permission by Mission Data International. Original article located here.

An exciting truth to learn as a world Christian is that each of us has a God-designated role in his global plan to reclaim the earth for His glory. How do we find our personal place in that plan? Where do you and I fit?


  • World Christian: Someone who commits their time, talents, and possessions to be used daily as effectively as possible for the advancement of the kingdom of God. This means becoming informed about the many unreached peoples of the world and taking an active role in the task of reaching them, through prayer, sending others, and/or going oneself.
  • Goer: Someone who believes God has called them to carry the gospel cross- culturally, as a full-time occupation. Sometimes referred to as a missionary; this kind of missionary leaves the comforts of home and the familiarity of their culture to spread the message of salvation in Christ to those culturally distinct from them in foreign lands.
  • Sender: Someone who deems their most important contribution to world evangelization to be staying in their home country and living in such a way as to support most effectively the maximum number of “goers” as they are able. This does not preclude their primary involvement in world evangelization as expressed by their reaching the lost around them.

The Cast of Characters

In God’s plan, there are two basic categories which we want to examine. These are senders and goers. Most people believe that there is a very small number of Christians who are called to be missionaries, or goers. This leaves all the rest, ipso facto, as senders.

Not true. You see, just as surely as God calls some to go, He calls others to stay. And what he desires most of all is your obedience.

The Profile of a Goer 

How do you know if you are to be a goer? First, you may find that you have a burden for peoples of other cultures to come to the Lord. More than that, you have a desire to take the gospel message to them.

Goers often feel inadequate for the task. They struggle with the thought of leaving family and friends behind. Sometimes they even wish they had a good paying job and could buy all the “niceties” of life.

What keeps them going is a driving desire for God to receive the full glory due him from all the nations and for all peoples to have the opportunity to hear the gospel. It makes the sacrifices worth it.

Goers have heard all the statistics of how many are lost without Christ and have brought that need to the Lord in prayer. This very act of considering the need and praying for a solution has led them to be the solution. The Lord of the harvest has spoken clearly. The goer goes forth in obedience to His command.

The Profile of a Sender

The sender must be just as sure of his call as the goer. It is a call to counter-cultural living. Our culture calls us to live for self, but the sender lives for the glory of God and the advancement of His kingdom.

Like the goer, the sender has a burden for peoples of other cultures to come to the Lord. But having assessed how God has shaped him and the place that God has called him to fill in the body, the sender concludes that he can best advance the kingdom by sending others.

A sender may be a business man who leads his family in living a simple lifestyle so they can support several missionaries. Or a sender may be a missions-minded pastor who knows he is called to remain in his country, but works hard to motivate his congregation to be effective senders and to raise up goers from their midst. A sender may be a professor who trains those who go. Or a blue-collar laborer who devotes several hours weekly to praying for several missionaries.

A sender isn’t a washed-out missionary or a goer who never made it. God calls us all to be involved in world evangelization and He calls many to be senders in His plan.

Sender or Goer?

How do you decide if you’re called to be a sender or a goer? Here are some guidelines:

  • Seek the Lord with all your heart. Ask him to purify your motives and ambitions, so that you do nothing out of guilt or selfish.
  • Ask the Lord to give you his heart for the lost. Let Him break your heart with their needs.
  • Check out all the options available to you.

~What could you do overseas?

~Where could you serve?

~What kind of an impact do you think you might have overseas?

~What can you do in your country?

~What kind of an impact might you have at home?

~What might be your potential sending ministry?


  • Evaluate where you might be most effective: as a sender or as a goer.
  • Discuss your findings with those who know you well: parents, pastor, campus ministry staff, professors, close friends. Ask them what they think your spiritual gifts are and where they think you’d do well serving the body of Christ
  • Make a decision and go for it!


The Call 

Someone once said, “If God calls you to be a missionary, don’t stoop to be a king.” To be anything other than what God calls you to be is to be less than what He calls you to be. And if God puts the desire in you to be a missionary, you won’t find satisfaction in doing anything else. You may come to this conclusion by looking at all the facts and realizing that your only legitimate response is to become a goer. Or you may come to it by getting some kind of sense from the Lord that this is what you are to do. Once you make the decision that you are called to overseas ministry and the Lord confirms it, don’t be swayed. Walk in obedience to the revealed will of God for your life.

Then again, after hearing the facts, seeing the needs, and praying for wisdom, you may come to the conclusion that your best contribution would be as a sender. Don’t feel second- rate. Don’t seek to explain to all the goers why you feel you should stay. Show them why you are staying by being the best sender you can be for the glory of God. Don’t get sucked into self-fulfillment and our culture’s system of satisfaction. Live for the glory of God among the nations.

God has a global plan. Each of us has a role to play in it. It may be as a sender or a goer. What is your role? Are you committed to playing your part?

Recommended Reading: “Cross-Cultural Servanthood,” by Duane Elmer

WIM senior missionaries were recently asked the question, “From the perspective gained during your time on the field, what additional study materials or preparation would you like to have received during your training?”  One answer repeatedly surfaced. The single most-frequent response revealed a desire for greater understanding of how to live and work cross-culturally. With a goal of addressing this need, for the past several years WIM’s required reading for new missionaries includes the book, Cross-Cultural Servanthood, by Duane Elmer, among others.

Concerning this book, missionary Chad Pennington says, “This book does a great job of highlighting Biblical principles of leadership and how to apply those principles to missions and cross-cultural ministry.”  He reiterates that, if we endeavor to lead in the way Jesus led, we must be serving others. As cross-cultural ministers of the Gospel, we must intentionally remain humble and teachable, ever learning from the people we are called to serve.  Our attempts to minister to people of a different culture are problematic, if we fail to dedicate the time necessary to learn well the culture and its values. We must remember that we have much to learn, and God is able to teach us and shape us into His perfect will, even through the culture we are called to serve.

Missionaries and other people in ministry must always be purposeful in seeking the guidance of the Holy Spirit, “to ensure that we are leading in a way that honors Christ and serves those who look to us for direction.”  In the end, if the people to whom we are called to minister view us as leaders, hopefully it is because we have modeled servanthood, just as Jesus did. Serving as Jesus did will demonstrate how to serve, in practical terms—for the benefit of those who would follow our example.

If you have not yet read this book, I would encourage you to put it on your short-list of books to read.
