Ministry - calling or profession?

Jeremiah. 20.9 "But his word was in mine heart as a burning fire shut up in my bones" Preachers, does the word of God burn in your heart as it did in the heart of the prophet Jeremiah? Does the word burn so hot that you are compelled to preach regardless of the cost? Is the ministry a calling that you are determined to follow regardless of cost, remuneration, or opposition?
