Where did the idea of being "called to preach" come from?

The church loves to use the idiom *called to preach .* It's the idea that (for the purposes of this question) God calls some people to preach or pastor and He doesn't call others. A person might say "...I felt God's call to preach " I'm not talking about the general call to salvation or that God gives certain gifts to some and not others, but about the specific colloquialism of *"...called from God to be/not be a pastor*." Where did this idea come from? 1 Timothy labels it a desire, not a calling. > **1 Timothy 3:1 KJV** This is a true saying, If a man desire the office of a bishop, he desireth a good work. Most every other translation says *aspire*, not calling. Are these thing synonymous? When did it start being referred to as a calling and not a desire? --- ***Why I ask***: A "calling" from God is a highly debated thing, whereas a "desire" is something everyone knows the definition of. Some young believers may be becoming dissuaded from their *desire* to lead in their local church because they've been incorrectly convinced that they need some fantastical *"clouds-parting-in-the-sky"* experience from God.
