Sanctification is complete on the day of glorification or death which ever comes first for the Saint. Sanctification is a life long work done by the Spirit within the believer.
Hebrews 12:21-24
King James Version
21 And so terrible was the sight, [that] Moses said, I exceedingly fear and quake
22 But ye are come unto mount Sion, and unto the city of the living God, the heavenly Jerusalem, and to an innumerable company of angels,
23 To the general assembly and church of the firstborn, which are written in heaven, and to God the Judge of all, and to the spirits of just men made perfect,
24 And to Jesus the mediator of the new covenant, and to the blood of sprinkling, that speaketh better things than [that of] Abel.
