Sanctified through the law

D&C 88 discusses sanctification and eternal life. We are sanctified through the law. We need to be sanctified to receive celestial glory. This sanctification comes through Christ. Fulfilling the measure of our creation is to be crowned with glory and live forever with the Eternal Father. The celestial kingdom was created for man to inherit.
