As St. Paul wrote to the Colossians:
That's why I work and struggle so hard, depending on Christ's mighty power that works within me. (1:29)
In many ways, that link--profession and personal vocation--is broken today. All of the talents one possesses have been breathed into people by the Creator for a divine purpose, that is, to build the Kingdom of God.
As Pope Francis tweeted earlier this year:
"A credible witness to truth and to the values of the Gospel is urgently needed."
