Calling means that everyone, everywhere, and in everything fulfills his or her (secondary) callings in response to God's (primary) calling.
If there is no Caller, there are no callings - only work.
Calling is not only a matter of being and doing what we are but also of becoming what we are not yet but are called by God to be.
Calling is a 'yes' to God that carries a 'no' to the chaos of modern demands. Calling is the key to tracing the story line of our lives and unriddling the meaning of our existence in a chaotic world.
In working out our callings, we are to perform for one audience, the audience of One.
