I found this scripture and had to ask this question to the preachers and ministers.

Do you preach from your heart or to keep a paycheck?

Galatians 1 : 10 - 12 (Paul, an apostle)
For do I now persuade men, or God? or do I seek to please men? for if I yet pleased men, I should not be the servant of Christ. But I certify you, brethren, that the gospel which was preached of me is not after man. For I neither received it of man, neither was I taught it, but by the revelationof Jesus Christ.
