Sanctification is an ongoing transformation within a maintained consecration, and it engenders real righteousness within the frame of relational holiness. Regeneration is birth, sanctification is growth. Regeneration was a momentary monergistic act of quickening the spiritually dead. As such, it was God's work alone. The standard to which God's work of sanctifying his saints is directed is his own revealed moral law, as expounded and modeled by Christ himself.
Believers find within themselves contrary urgings.
This conflict and frustration will be with Christians as long as they are in the body.
