What is missionary success? Why so many of our definitions leave us feeling empty
By Ken Guenther, SEND U —
In an earlier article, I listed 10 definitions of missionary success that miss the mark
— many of them stemming from my own experience. As promised, here is my attempt to critique these inadequate definitions of success.
2. Fitting in well into a new culture.
This can be true of someone who is not even a believer! I am reminded of Pearl Buck and other early 20th century missionaries to East Asia who fell so in love with the culture and religion that they ended up rejecting their evangelical faith. See “The Conversion of Missionaries”
by Lian Xi.
4. Nurturing a healthy, loving family.
Without question, if you are married, a healthy, well-adjusted family is foundational for effective ministry. But if our primary goal is to nurture the health and happiness of our family, then we have taken a means and made it an end in itself. We become focused on ourselves, our needs, and our enjoyment of life, rather than on being a blessing to others. I recognize that, historically, missionaries have been guilty of neglecting their families for the sake of the ministry. But the pendulum can also swing the other way. We can get so wrapped up with family matters that we have no time for anyone else.
6. Helping needy people.
I recognize that alleviating suffering is considered by many to be the heart of the mission of God. I disagree, and I believe that Scripture also disagrees. I do not want to give the impression that evangelism is the only mission activity of any importance. I believe that effective proclamation of the gospel results in communities of faith that are committed to social justice and helping the poor. I also believe that missionaries can begin by helping the poor as their primary ministry focus, but that any holistic approach to gospel ministry must include sharing the good news that God is concerned about saving people from physical suffering on earth, and especially from eternal suffering. See John Piper’s address to the 2010 Lausanne Congress.
7. Completing the tasks you were given to do
. The fallacy in this definition is that it assumes that our responsibility to God ends with fulfilling our responsibilities assigned by our mission leaders. We may have done everything our mission asked us to do, but have we done what God asked us to do? I do not want to set our calling at odds with the assignments given by mission leadership, but I also want to acknowledge that mission leadership can never fully comprehend everything that God may want us to accomplish by faith in his Spirit’s enabling. Our calling, our spiritual gifts, and our message come from God, not from mission leadership, and so ultimately we will have to give account to the One who has entrusted them to us.
9. Meeting a strategic need.
The aspiration to meet a strategic need is obviously not wrong in and of itself. It can be motivated by a desire to be a good steward of God’s gifts and resources. But it can also be driven by a desire to feel important, to promote ourselves. Furthermore, this definition gets us into trouble when we are asked or prompted to do something that does not seem “strategic,” like showing compassion to a beggar. Much of what we are doing as missionaries and in the kingdom of God will not be noticed by this world (or even by national church leaders). As servants of the King, we must be content to faithfully fulfill our King’s assignments, and let him determine how our efforts will contribute to his kingdom.
Remember, all of the above are good aspirations and commendable accomplishments. But I don’t think any of them, by themselves, define a “good missionary.” Some of them could just as easily be done by someone that is not a believer. Some of them (like numbers 9 and 10) are too narrow and can belittle less-strategic ministries that are truly God assignments. Some of them are too focused on ourselves and our own well-being.
