Hi Bubbles. The way I think its best to answer this question is to first start off with your religion and your involvement, such as church, praying to whoever you pray to and whatever you do, and connecting this with Loma Linda's commitment to outreach programs and clinics.
Loma Linda is highly commited to outreach programs, clinics, and involvement with programs outside of America.
Show how your involvement in your religion connects and follows their view about outreach programs and what you have learned from it. Be specific as you know the limit on those essays.
Hope it helps, ill check again if you have questions.
