The same God who knit us together in our mother's womb, who formed our emotions and character and innate worth, who orchestrated our lives up until this point--that God placed us where we are today. In our jobs, in our families, in this place.*
There are some moments when the light of that purpose burns clear and bright but others when we can barely discern it through the fog. Regardless, we must work "as working for the Lord." Serving a heavenly Christ, even through our earthly tasks.
*While this is generally true, if you should find yourself in an evil place among those who would harm you, that is not God's doing. God is never the author of evil and you should strive for freedom from that harm.
