Commenting on Acts 20 ~
The model covered the whole time Paul spent in Ephesus, right from the first moment he arrived until he left. That period has already been described in Acts 19:1-20; and if that were the only account of it, we might well have formed the impression that it was two years and three months of the rigorous public preaching of a forceful man, performing extraordinary miracles and achieving triumphant success. What a different side of things the present address paints in. Here is what the work of serving the Lord was really like, and here is the real man who actually did it: marked by humility, often reduced to tears as he faced the plots of the Jews against him (Acts 20:19, 31), and constantly beset with trials. But see his moral courage and generosity: ‘I have not hesitated to preach anything that would be helpful to you,’ he declares in verse 20; and again in verse 27, ‘For I have not hesitated to proclaim to you the whole will of God.’
