Grace Reigns through Jesus Christ !
Rom 5:15-21
15But not as the offence, so also is the free gift. For if through the offence of one many be dead, much more the grace of God, and the gift by grace, which is by one man, Jesus Christ, hath abounded unto many.
16And not as it was by one that sinned, so is the gift: for the judgment was by one to condemnation, but the free gift is of many offences unto justification.
17For if by one man's offence death reigned by one;
much more they which receive abundance of grace and of the gift of righteousness shall reign in life by one, Jesus Christ.)
18Therefore as by the offence of one judgment came upon all men to condemnation; even so by the righteousness of one the free gift came upon all men unto justification of life.
19For as by one man's disobedience many were made sinners, so by the obedience of one shall many be made righteous.
20Moreover the law entered, that the offence might abound. But where sin abounded, grace did much more abound:
21That as sin hath reigned unto death,
even so might grace reign through righteousness unto eternal life by Jesus Christ our Lord.
What Adam did gave result to death reigning upon all whom He represented, but what Christ did gave result to Grace reigning upon all whom He represented.
Grace reigns even moreso through the Covenant Head , the Lord Jesus Christ, than death does reign through the Covenant Head Adam. Now for anyone who died because of their sin in Adam, be not raised up unto Life Eternal because of Christ, that would mean that Adam's Death results prove more powerful than Christ Grace results, that Adam's deed upon his posterity was more effectual than Christ deed upon His Posterity, who died in Adam.
Thank God though thats not the case, for the Grace that comes through the Righteousness of Christ's deed shall save all those He represented from the death they received from their Representative Adam, Grace will always reign triumphant over sin and death.
