Is the ministration of the Spirit more glorious than the ministration of the Law?
Yes. The ministration of the Spirit, which is indicative of grace, is rather glorious and even more glorious than the ministration of the Law. The Law was written and engraven in stones and can only condemn; its glory was to be done away, while grace takes its place.
Les explains that the ministration of death, written and engraven in stones, was glorious, so that the children of Israel could not steadfastly behold Moses' face for the glory of his countenance, which was to be done away. Many assume the veil covered Moses because he was radiant, but Les says the veil was actually veiling the passing away of the Law. Paul then argues that if the gloriousness of the Law fades away, what takes its place and is even more glorious? Grace. Therefore the ministration of the Spirit, which is indicative of grace, is more glorious than the ministration of the Law.
How shall not the ministration of the spirit be rather glorious?
