What is the difference between the Holy Spirit and Pneuma Hagion?
The Holy Spirit is the person; Pneuma Hagion is the power from on high that He gives to believers. It is exercised through the person of the Holy Spirit, enabling them to confront the old nature, live victoriously in the flesh, and let the Spirit run the race for them.
Les teaches that the Holy Spirit is the person, while Pneuma Hagion is the power from on high that is exercised through the person of the Holy Spirit. Believers cannot confront the old nature or live victoriously in the flesh without that power. This is taken by faith: one can draw on Him rather than forcing oneself to be a law keeper, and it comes naturally to let the Spirit run the race for us.
