Yeah, see this is the scripture that I was talking about. A lady I know said that ministers who are called by God give up everything to follow him, including their previous jobs. I doubt that this is ALWAYS the case. I'm wondering if there was any evidence besides this verse, one way or another, particularly with regard to Paul.
I believe these passages indicate that Paul continued working...
"So, affectionately longing for you, we were well pleased to impart to you not only the gospel of God, but also our own lives, because you had become dear to us. For you remember, brethren, our labor and toil; for laboring night and day, that we might not be a burden to any of you, we preached to you the gospel of God." - 1 Thes. 2:8-9
"For you yourselves know how you ought to follow us, for we were not disorderly among you; nor did we eat anyone’s bread free of charge, but worked with labor and toil night and day, that we might not be a burden to any of you, not because we do not have authority, but to make ourselves an example of how you should follow us." - 2 Thes. 3:7-9
"To the present hour we both hunger and thirst, and we are poorly clothed, and beaten, and homeless. And we labor, working with our own hands." - 1 Cor. 4:11-12
"My defense to those who examine me is this: Do we have no right to eat and drink? Do we have no right to take along a believing wife, as do also the other apostles, the brothers of the Lord, and Cephas? Or is it only Barnabas and I who have no right to refrain from working? Who ever goes to war at his own expense? Who plants a vineyard and does not eat of its fruit? Or who tends a flock and does not drink of the milk of the flock? Do I say these things as a mere man? Or does not the law say the same also? For it is written in the law of Moses, 'You shall not muzzle an ox while it treads out the grain.' Is it oxen God is concerned about? Or does He say it altogether for our sakes? For our sakes, no doubt, this is written, that he who plows should plow in hope, and he who threshes in hope should be partaker of his hope. If we have sown spiritual things for you, is it a great thing if we reap your material things? If others are partakers of this right over you, are we not even more? Nevertheless we have not used this right, but endure all things lest we hinder the gospel of Christ... But I have used none of these things" - 1 Cor. 9:3-12, 15
