Acts 18

And he found a certain Jew named Aquila, born in Pontus, who had recently come from Italy with his wife Priscilla (because Claudius had commanded all the Jews to depart from Rome); and he came to them.  So, because he was of the same trade, he stayed with them and worked; for by occupation they were tentmakers...So he began to speak boldly in the synagogue. When Aquila and Priscilla heard him, they took him aside and explained to him the way of God more accurately. vv.2-3,26

Read chapter 18
Work relationships are just as much a ministry and more because of the constant time together.  Paul, Aquila and Priscilla are tentmakers and no doubt that they talked about the scriptures while they worked and Paul sharing of who Jesus Christ is and his commission from Him.  This building of friendship with Christ at the center gave wisdom to Priscilla and Aquila to then discern and share truth with others, Apollos we see here in this chapter.  And so much more than sharing with Jesus Christ is as God but "accurately" with scripture that pointed and proved it and through what God was currently doing since Apollos only knew up to John's baptism.  
So what do your work relationship look like?  Do people in your work know you're a believer?  Do you talk about scripture together with those that believe or don't believe?  Do you desire to have the scruples more accurately known to you?  Do you understand how God is currently working today since the close of the Bible writings?
