God’s people, whom he has called out of the world to himself, are a sanctified people… To sanctify is to set apart from common use, a setting a part for God.. Separated from the perishing world to be “vessels of honour for the master’s use” (II Tim. 2:21)… Every sin is a kind of sacrilege, it steals a holy thing away from God… To sanctify is to cleanse… We all come into the world polluted with the stain of sin, which is purged and done away by degrees, and at death wholly. To be sanctified is more than to be purified; for besides the expulsion of sin, there is an infusion of grace, a disposition wrought clean contrary to what we had before… “a new heart and a new spirit” (Ezek. 36:25-27).
Thomas Manton on the Epistle of Jude
