I read this thought-provoking quote this morning on Justin Buzzard’s blog.  It is from the book, Called To Ministry by Edmund Clowney.

"To miss your calling, follow this three-point program: assume that it begins in the future, decide that you don’t know what it is, and sit down to wait for the Lord’s call.
No, he has already called you–to be a Christian. Fulfill that call with all your heart and you will learn in his time what ministry is yours."
