I was thinking today about how many people my age, and even older than me, ask themselves that question. Many people wonder why they exist, and what there purpose is.
My purpose in life, and the purpose of everyone's life, is to show the love of Jesus! I want so badly to just shine for Him in a dark and lost world. So that is our purpose. To emulate Jesus the best that we know how, and to share him with those, even in far and distant countries. God help us to actually to this.
