Was Paul in ministry for money or fame?
No. Paul was not in ministry for money or personal gain. The context states he was not in it for wealth. He renounced hidden things of dishonesty, did not walk in craftiness, and did not handle God's word deceitfully, unlike a street salesman or hawker out for profit.
Les teaches that Paul declared, 'Seeing we have this ministry, as we have received mercy, we faint not.' Paul then said, 'We have renounced the hidden things of dishonesty, not walking in craftiness, nor handling the word of God deceitfully.' Les emphasizes that Paul was not in this for personal gain and not in it for wealth. The Greek idea of corrupt in verse 17 was like a street salesman or hawker out simply for profit, but Paul was not watering down his message. He was not giving an adulterated or corrupted message. The context does not mention fame, but it explicitly denies personal gain and wealth as Paul's motive.
But have renounced the hidden things of dishonesty, not walking in craftiness, nor handling the word of God deceitfully; but by manifestation of the truth commending ourselves to every man’s conscience in the sight of God.
