2 Cor. 11: 7 Was I wrong when I humbled myself and honored you by preaching God’s Good News to you without expecting anything in return? 8 I “robbed” other churches by accepting their contributions so I could serve you at no cost. 
When Paul began to preach the Gospel in Corinth, he didn’t charge for his services. He worked during the day as a tent maker with Priscilla and Aquila and preached the Gospel in the evenings. There is wisdom in not charging for evangelism. Many times today, unbelievers see preachers as greedy and after their money. Unfortunately, there are some unscrupulous preachers who do take advantage of others. This kind of thing stops the advance of the Gospel.
Paul was humble and didn’t elevate himself as someone special who deserved great amounts of money. He allowed other churches to send financial support and to give prayer support. This involved not only himself but others in the kingdom. It was a team effort. It allowed the church to come together to build God’s kingdom, Paul wasn’t the “rock star” pastor out to build a name for himself.
How about you? How can you become part of a team to build the Kingdom of God?
