If you ever come out for missions because you think that it is fun, you may be out for a surprise. Mission is not just fun, a times it is challenging. However, what always draw my heart to missions is the fulfillment in it, the experience and the lessons involved. Doing Missions has been renewing, fulfilling and a time when my spiritual life is rejuvenated. This I believe is what people will find in missions but they find it easy to say that it was fun doing it.
May be it is because of lacking a language to express the true feeling after doing mission. Some may be mislead by the term fun and hence give themselves for mission thinking fun only to discover challenges beyond imagination. Reading books about missions will tell you that those who have done it before did not do it because of fun but because of calling. If you talked with many missionaries, they will tell you that the reason they continue to live among unreached people in challenging areas where comfort is long forgotten is because of a call. They heard a call and so they went out to serve and to preach the Gospel of the one who called them. They fear that going back home will be a disappointment to the caller. Since the caller is supreme, they are assured of His protection.
