Pneumatic Soteriology: Regeneration, Indwelling & Sanctification
The New Birth, Temple of the Spirit, Fruit of the Spirit, and Union with Christ
The Holy Spirit applies redemption to the elect by effecting supernatural regeneration (the new birth), permanently indwelling the believer's body as a temple, and cultivating progressive sanctification through the Fruit of the Spirit.
Regeneration: The Supernatural New Birth
In John 3:3-8 , Jesus teaches that entrance into the Kingdom of God requires being born again (anothen) from above by the Spirit. Regeneration is the instantaneous, monergistic work of the Holy Spirit imparting spiritual life to a dead soul ( Ephesians 2:1-5 ), removing the stony heart and giving a heart of flesh ( Ezekiel 36:26 ).
The Permanent Indwelling of the Holy Spirit
Under the New Covenant, the Holy Spirit does not merely visit individuals transiently for external tasks, but permanently indwells every true believer ( Romans 8:9-11 ). The believer's physical body is consecrated as a living sanctuary: 'Do you not know that your body is a temple of the Holy Spirit within you?' ( 1 Corinthians 6:19 ).
Sanctification and the Fruit of the Spirit
Sanctification is the ongoing, cooperative work of the Holy Spirit conforming the justified believer to the moral image of Christ . By walking in the Spirit, the believer overcomes the passions of the flesh and bears the singular Fruit of the Spirit: love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control ( Galatians 5:22-23 ).
