“Your letters to friends and family back home have a profound effect on the cause of world evangelisation. Writing a good letter is hard work. We won’t pretend it isn’t. But a good letter is a catalyst for prayer support and for enlarging the vision of others for what God is doing in the world. It is also the means of planting the seed in the hearts of those who will follow you into cross-cultural service tomorrow. The discipline on your part is small compared to the eternal value of letters that are prayerfully and skilfully written.” – Media Associates International.
