Paul taught that everyone who is called to Christ is also called to serve. All ministry is the Lord's work: God assigns the tasks and uniquely gifts a variety of individuals to work together to fulfill His plan, for His glory. Noting that great opposition often accompanies effective ministry, Alistair Begg encourages us to serve God wherever He has placed us and doing whatever He has given us to do.
1 Corinthians 16:5-12
