New Defender's Study Bible Notes
20:21 repentance toward God, and faith toward our Lord Jesus Christ. Both repentance and faith were essential components of the message of Paul to non-Christians, whether Jews or Gentiles, and so should they be of our witness today. Repentance toward God and faith in Christ are like two sides of the same coin. They are distinct, yet neither true repentance nor true faith exists without the other.
20:26 pure from the blood. Paul is probably referring here to the principle in Ezekiel 3:17-21.
20:27 counsel of God. Jesus had commissioned the apostles to teach the disciples to “observe all things whatsoever I have commanded you” (Matthew 28:20), and Paul endeavored to do just that in all the churches for which he felt responsible. It is important that each church, especially its leaders, seek to teach its members the whole Word of God, not to concentrate on a few pet doctrines.
20:28 overseers. The word “overseers” is the same as “bishops.” Since these men were the “elders of the church” (Acts 20:17), it follows that the offices of “elder” and “bishop” were the same in the early church. In the Greek, “elder” is presbuteros (from which, of course, we get our ecclesiastical term “presbyter”) and “bishop” is episkopos (from which “episcopal” is derived), meaning simply “overseer.” The two terms are again equated in Titus 1:5,7. The word “pastor” is the same as “shepherd” (Greek poimen), and the elders (or bishops) have the duty of “feeding” the “flock” for which they are responsible. See also I Peter 5:1-5.
