God has a plan for your life which no other man can fulfil. No two leaves, no two jewels, no two stars, no two lives, are alike. There is no man in all the world who can do your work as well as you.

God has given you a particular kind of personality. He has also created a particular circle of individuals who can be reached and touched by that personality as by none other in the world. And then He shapes and orders your life so as to bring you into contact with that very circle.
(James H. McConkey)
