God may ask you to do something you were not expecting and it may be in a field that you have zero experience. I say this because it happens all the time. God chose Gideon an ordinary guy, who threshed wheat in hidden places, to lead the military and be a prophet and judge for the Israelite people.
[Judges 6:12] And the angel of the Lord appeared to Gideon and said, “The Lord is with you, O mighty man of valor.” God was well aware of Gideon's potential long before Gideon was. Some people would be shocked to learn what they are capable of doing if they were simply willing to give something new a try. If God gives you a task outside your profession then just do it!
