Those of us who have secular jobs have to work hard in order to earn our living. We must be faithful, committed employees in order to escape from being fired, and earn raises. The same thing should apply to Christian Ministers. They, too, should receive financial provided that they do their job faithfully. Of course, preaching is not a normal business that generates revenue in the normal ways. Therefore, faithful churchgoers need to willingly and joyful give money to support those who minister to them, as the Bible clearly indicates. Listen to the words of the Apostle Paul as he teaches this principle in the book of I Corinthians:
Do I say these things on human authority? Does not the Law say the same? 9 For it is written in the Law of Moses, “You shall not muzzle an ox when it treads out the grain.” Is it for oxen that God is concerned? 10 Does he not certainly speak for our sake? It was written for our sake, because the plowman should plow in hope and the thresher thresh in hope of sharing in the crop. 11 If we have sown spiritual things among you, is it too much if we reap material things from you? 12 If others share this rightful claim on you, do not we even more? (I Corinthians 9:8-12 NIV)
What Paul is saying here is that those who minister faithful among the churches in spiritual things should should receive financial compensation from the churches that they are ministering to. It is good for a church to pay a full-time minister enough money to allow him to spend most of his time in serving the church directly, rather than having to waste much effort in putting their food on the table. I believe that those who serve well are deserving of regular raises just as those of us with a good work ethic naturally expect regular raises at our own jobs.
