ministry - God's workers

why does going abroad to live and work always equate to "full time ministry"?

why do we say these things? full time ministry is every day of every Christian's life.

why does someone have to go abroad or seminary to be considered "one of God's workers"?

why is someone who happens to go abroad to work and live, considered one of God's workers? why isn't every Christian in that category?

I'm praying for patience [who isn't... :) ] and that I will be a better worker.
