Dear [insert name here],
     Can you envision a land where cows are holy, animal sacrifices are a weekly occurrence and human cremations take place daily? I want to share with you a challenging ministry opportunity I believer God has presented to me. During [insert dates here], I am planning to go to [insert country & city/region here] with a team from Twin Lakes Church.
     Our two-week trip will focus on [insert what you’re doing here; e.g.: “Hindu and Buddhist cultures in this area of the world that is often referred to as ‘the heart of darkness.’”] The purpose of our trip is fourfold: [E.g.:

First, we will be allowing God to work in our lives through the personal enrichment that comes from this type of a mission trip.
Second, this Prayer Journey will help us focus our individual prayers by traveling to a foreign land and praying “onsite with insight.” We will pray for the Hindu and Buddhist people that God may open their eyes and hearts to the message of Jesus.
Third, we will be visiting an “unreached people group” of which less than 1% is Christian. First Christian Church has adopted the Newar people group and is assisting in bringing them the gospel. We will be working with some Newar churches to help them grow in their Christian walk.
Fourth, we will encourage local Christians in Bangkok and Kathmandu. Our presence will bolster their spirits and support their work. We will visit many small villages in Nepal where we will develop relationships with the Christians there.]

I'm excited about the opportunity and experience that lie ahead. I hope you see the value in what we will accomplish. As you can imagine, a trip like this requires financial support from a number of people. I need to raise [insert amount here] by [insert date here]. If you can support me in a financial way, I would be very grateful!  And, most importantly, I also need your prayer support.  Prayer is the fuel that will allow us to be successful as we follow God's leading in ministry in these countries.  Without prayer, nothing will happen.
     If you would like to be part of this mission through your financial support, send a check to:   [insert your address here].
     Envelopes are enclosed for your convenience. Please make your check payable to Twin Lakes Church and write [insert team/country name here] on the memo line.  Please do not write my name anywhere on the check--the IRS has informed us that doing so will prevent your gift from being tax deductible.
     While money is important, it comes in a distant second to my need for your prayer support. Since prayer support is so important to the success of this mission, I would like to know if I can count on you in that area. Enclosed is a [e.g. a card or bookmark] that you can put in your Bible, on your bathroom mirror, on the refrigerator or anywhere else you will see it at least once a day. Please pray daily for the areas listed!

     Sincerely/God Bless/Best Regards/Because they haven't heard/etc.
