10 of those

God has given us a special gift in Paul's farewell message to the Ephesian elders (Acts 20:17-38). There is really nothing else in the New Testament comparable to this passage. In Acts 20: Fierce Wolves are Coming - Guard the Flock, Alexander Strauch provides an in-depth yet practical exposition of this extraordinary portion of Scripture. 

History amply demonstrates that the truths of Paul's message cannot be overstated or repeated too often. The appalling, centuries-long failure to stop false teachers from invading churches can be traced directly back to ignorance of or disobedience to Paul's prophetic warnings to the Ephesian elders. Paul's instructions and pleas to the Ephesian elders are just as critically needed today as they were that day on the shores of Miletus. "Any church elder who does not know the content of Paul's message to the Ephesian elders is ill-equipped to lead and protect God's people." Alexander Strauch
