Dear Parents. I am serious about this. Please click on the link below to the PDF of this missionary booklet. This is the best material you will find on how to help and encourage your missionary when they are having a hard time (it happens to the best, every day). Please be familiar with the information here so you can cheer from home with helpful suggestions. We love you and are grateful for your love and support.
