Note 6 at Acts 20:25: Paul was not just "left in the dark" about what was going to happen to him. He knew through his communion with the Holy Ghost that he would not be coming back to Ephesus. He didn't know the details (v. 22), but he knew the overall plan (v. 23). Thus Paul illustrates how the Lord wants to show us things to come (Jn. 16:13) and challenges every believer to walk in this mostly untapped ministry of the Holy Ghost (see note 83 at Jn. 16:13, p. 499).
