The Washington Post had an interesting piece titled Teen missions being retooled. Here are some snippets.
WASHINGTON — Not long ago, the families of Fairfax (Va.) Presbyterian Church spent thousands of dollars to fly their teens to Mexico for eight days of doing good. They helped build homes and refurbish churches as part of an army of more than 1 million mostly Christians who annually go on short-term international mission trips to work and evangelize in poverty-stricken lands.
Yet even as those trips have increased in popularity, they have come under increased scrutiny. A growing body of research questions the value of the trips abroad, which are supposed to bring hope and Christianity to the needy of the world, while offering American participants an opportunity to work in disadvantaged communities, develop relationships and charge up their faith.
Critics scornfully call such trips “religious tourism” undertaken by “vacationaries.” Some blunders include a wall built on the children’s soccer field at an orphanage in Brazil that had to be torn down after the visitors left. In Mexico, a church was painted six times during one summer by six different groups. In Ecuador, a church was built but never used because the community said it was not needed.
I don’t see how people serving on mission trips on their vacations is a bad thing. Of course, non-value added activities like re-painting the same thing or building inadequate or unnecessary structures is ridiculous. But those things can be prevented with good planning.
I heard of parts of Mexico referred to as the “Methodist ruins” because many churches started projects and didn’t follow through. Just because you are doing a good deed doesn’t mean you don’t need wisdom, discernment, superior planning and organization.
The church is sending out smaller teams of experts to work on projects with partner churches. For example, it is sending information technology professionals who are fluent in Spanish to a church in the Dominican Republic to train members in computer skills so they can get better jobs, MacDonald said.
Despite the concerns with trips abroad, their popularity is soaring. Some groups go as far away as China, Thailand and Russia. From a few hundred in the 1960s, the trips have proliferated in recent years. A Princeton University study found that 1.6 million people took short-term mission trips — an average of eight days — in 2005. Estimates of the money spent on these trips is upward of $2.4 billion a year. Vacation destinations are especially popular: Recent research has found that the Bahamas receives one short-term missionary for every 15 residents.
At the same time, the number of long-term American missionaries, who go abroad from several years to a lifetime, has fallen, according to a Wheaton College study done last year.
The short-term mission trip is a “huge phenomenon that seems to be gaining in momentum rather than waning,” said David Livermore, executive director of the Global Learning Center at Grand Rapids Theological Seminary, who studies the trend.
Participants care for orphans, hold Bible classes, evangelize, paint homes and churches and help AIDS patients, among other tasks.
But research has found that the trips tend to have few long-term effects on the local people or on the mission travelers. Some projects take away work from local people, are unnecessary and sometimes dangerous.
I wonder what groups they researched. That has not been my experience. Then again, we typically send teams to the same places over and over so that relationships are built and we can be sure we are making a difference.
“I really don’t think that most people are trying to be ugly Americans,” said Glenn Schwartz, executive director of World Mission Associates and author of When Charity Destroys Dignity. “But they’re misinformed and don’t realize how their good intentions can go awry.”
Mission groups also often bring their own experts and ignore local authorities on the ground.
In Monrovia, Liberia, three years ago, tragedy occurred when visitors built a school to their standards instead of Liberian standards. During the monsoon season, the building collapsed, killing two children, Livermore said.
Understanding the local customs and needs is crucial. We always defer to local building practices.
Critics also question the expense involved in sending people long distances. Short-term missionaries pay $1,000 each, or far more, in plane fare and other expenses to get to remote destinations.
A 2006 study in Honduras found that short-term mission groups spent an average of $30,000 on their trips to build one home that a local group could construct for $2,000.
“To spend $30,000 to paint a church or build a house that costs $2,000 doesn’t make a whole lot of sense,” said Kurt Ver Beek, a professor of sociology at Calvin College who conducted the research.
I think that misses the point. Mission trips aren’t just about the physical property being built or repaired. They are about relationships with the people, helping them in ways that are meaningful and lasting, sharing the Gospel and transforming the lives of those who go. It changes how you view the world.
And practically speaking, I’ve found that people who go on short term mission trips write more and bigger checks to help these areas, and they encourage others to do the same. Who better to tell people of the needs than those who have been there?
All of the objections brought up in the article could be dealt with by applying more wisdom and planning.
One. 
Lotteries are illegal unless the government runs them, and so are pyramid schemes like Social security.
A common objection to the assertion that God inspired the writings of the Bible is that men wrote it, so it must have mistakes. Sadly, I have often heard this from committed Christians.
