There are some people whom society treats as furniture people. Unnoticeable. Unimportant. They are rarely spoken to unless people have a complaint. Or want to use them as scapegoats. But they are the glue that hold the world community together. Teachers. Nurses. Social workers. Fire and Police men and women. Factory workers. Soldiers. Veterinarians. Bus drivers. Truck drivers. Migrant workers. Waiters and waitresses. Bakers. Salespersons. Beauty Salon operators. Bank tellers. Why should we think - or act - as if what they do is less important to society than the work of a Doctor, Developer, Corporation C.E.O?
St. Paul tells us that God has given each one of us special gifts to build up the Body of Christ - the community - and that the community needs every single person and every single gift: "There are varieties of gifts but the same Spirit." Every person and every gift is important, necessary. God knows how long that Corporation C.E.O would last driving a school bus! Jesus himself preferred fishermen and tax collectors for his world mission.
So I would say "Dream BIG - dream of your own special gifts given to you by God to build up love in your community. Be ANYTHING you want to be, and know that what you want to be is important! Believe in how necessary you are to this world!" Jean Vanier says it well - "We are not called by God to do extraordinary things but to do ordinary things with extraordinary love."
