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.
