1 Corinthians 9 : 12 If others be partakers of this power over you, are not we rather? Nevertheless we have not used this power; but suffer all things, lest we should hinder the gospel of Christ.

Paul says in this verse it was his right to have his living supplied by those he ministered to but did not require it of them because he did not want the to think that is why he ministered to them. He was trying to teach them a principle here that the people should support the one who ministers the truth of the gospel to them. False teachers are the ones who are in it for the money and so Paul endured not taking any support from the Corinthians so they would know he was bringing them the truth. A lot of ministers today feel it necessary to work outside the ministry in a secular  job but Paul is saying this should not be the case. Ministers should be able to supply all the needs of theirs and their family through the money received for their ministry if they are committed to it 24 hours a day. Some churches today are large enough that this happens but I feel, in the smaller churches, where usually you gain a better understanding of the word of God and it is not just a feel good church to gain more people and money, then the minister may have to have a secular job.  We should always be aware of the needs of anyone who ministers to us to know that they are taken care of if they are truly doing the will of God.
