I was sent a link to this great article for missionaries and their families. When facing a challenge while on mission, all do at some point, read this article and renew your faith, hope and pure love of Christ.
Letters to Struggling Missionaries
By Larry Barkdull
Second tip for today. If you are struggling, only write your mom or dad, or someone that will bouy you up, encourage you and edit your letters prior to posting on your blog. It is OK to have challenges and to write about them. (Not OK to post whining).
