Vocation
The word “vocation” is from Latin, vocatio.  It means “a call, summons”.  Vocation is more than employment or career.  Vocation is about knowing your purpose.  It means knowing that GOD created your heart with its desires, discovering the direction of your heart and then following it with passion and joy because that is who you are.  It means being true to yourself and to the GOD who created you.  Vocation is about destiny.
 Eric Greitens is 38 years old.  He is a Rhodes scholar and humanitarian worker turned U.S. Navy SEAL. He served multiple tours overseas fighting terrorist cells and received several military awards. Today, he is the CEO of The Mission Continues, a nonprofit foundation he created to help wounded and disabled veterans find ways to serve their communities at home.
These words are from his commencement address at Tufts University in May 2012: 
 "The best definition I have ever heard of a vocation is that it's the place where your great joy meets the world's great need.  For you to build that vocation will take both compassion and courage . . . We need all of you to find your vocation. To develop your joys, your passions, and to match them to the world's great needs."
We live life to the fullest when we know we are doing what GOD created us to do.  That is what makes it a “calling.”  Parenting is not about making great athletes or actors or CEO’s or plumbers.  It is about knowing what GOD made that child to do & to be, then preparing the way for them to get there or preparing them for the way to get there. It is about helping them discover their “vocation.” Ask them, “What is your great joy?” and “How will that help people?” When your children begin thinking in those terms, they are on the road of destiny.
