2 Corinthians 3:6-11

He has qualified us [making us sufficient] as ministers of a new covenant [of salvation through Christ], not of the letter [of a written code] but of the Spirit; for the letter [of the Law] kills [by revealing sin and demanding obedience], but the Spirit gives life. [Jer 31:31] Now if the ministry of death, engraved in letters on stones [the covenant of the Law which led to death because of sin], came with such glory and splendor that the Israelites were not able to look steadily at the face of Moses because of its glory, [a brilliance] that was fading, [Ex 34:29-35] how will the ministry of the Spirit [the new covenant which allows us to be Spirit-filled] fail to be even more glorious and splendid? For if the ministry that brings condemnation [the old covenant, the Law] has glory, how much more does glory overflow in the ministry that brings righteousness [the new covenant which declares believers free of guilt and sets them apart for God’s special purpose]! Indeed, what had glory [the Law], in this case no longer has glory because of the glory that surpasses it [the gospel]. For if that [Law] which fades away came with glory, how much more must that [gospel] which remains and is permanent abide in glory and splendor!
