Christian Ministry: Liberties and Limitations (1st Corinthians 9)

Are ministers in any form of Christian ministry entitled to payments for their roles and services in the body of Christ? Where does the right end and how far can sacrifices be made for the sake of the cross? In 1st Corinthians Chapter 9, Paul tackles the issue of Christian ministry, balancing out the rights of ministers to be compensated and where the line ought to be drawn, especially when the sake of the gospel may be put at stake.
