Acts 20:27

Paul had passed on to these elders what was truly profitable to them (cf. Acts 20:20). "The whole purpose of God" refers to God’s plans and purposes rather than a verse by verse exposition of the Scriptures. Their responsibility was to instruct the saints in more detail.

"As I write this, I am a retired preacher. I have made many blunders and have failed in many ways. But as I look back on my ministry, I can say truthfully that when I stood in the pulpit, I declared the Word of God as I saw it. I have the deep satisfaction of knowing that if I went back to any pulpit which I have held, I haven’t a thing to add to what I have already said. I don’t mean I couldn’t say it in a better way, but the important thing is that I declared the whole counsel of God. I have always believed that the important issue is to get out the entire Word of God." [Note: McGee, 4:604.]
