New Defender's Study Bible Notes
2:18 Father. Note the activity of all three persons of the Godhead in reference both to salvation and prayer. We have access to the Father only through faith in the Son and by the implementing work of the Holy Spirit. Note also the work of the Trinity: in redemption and forgiveness (Hebrews 9:14); the presence of the Trinity in our baptismal testimony (Matthew 28:19); in our experience of regeneration (Galatians 4:6); in our assurance and fellowship (II Corinthians 13:14); in witnessing (John 15:26); and in teaching (John 14:26).
