The free gift is of many offences unto justification !
Rom 5:16
16 And 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.
Justification here is stated as a Free Gift in light of our many offences, and it comes through the Person and work of Jesus Christ or His Blood for His Church, His Sheep.
For them, He shed His Blood to satisfy the sentence of the Law against them, The Law which they had broken, its punishment was Justly executed upon Him, as the Head of the Church, not for all men without exception ! This is being Justified by His Blood Rom 5:9
9 Much more then, being now justified by his blood, we shall be saved from wrath through him.
The word for Justify here means acquitted , the greek word dikaioó:
I make righteous, defend the cause of, plead for the righteousness (innocence) of, acquit, justify; hence: I regard as righteous.
That word acquit means:
to relieve from a charge of fault or crime; declare not guilty:
Once the Lord Jesus Christ tasted death for all whom He died as Per Heb 1:9, it is stated this Heb 1:3
3 Who being the brightness of his glory, and the express image of his person, and upholding all things by the word of his power, when he had by himself purged our sins, sat down on the right hand of the Majesty on high:
That word purged is the word katharismos and it denotes among other things :
a cleansing from the guilt of sins
Thats an acquittal from them, which is Justification !
When Christ died for the sins of the Church, all for whom He died, by that alone, they were actually Justified Rom 5:18
18 Therefore 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.
Yes, the Free Gift here is that which is also referred to in Rom 5:16
16 And 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.
Its Justification, or Acquittal from the guilt of sins they have committed. This is a Free Gift by Imputation to their Account because of Christ's Blood which cleansed them ! Heb 1:3 !
Back to Rom 5:18, the sentence of condemnation and death actually came upon the elect in Adam, their Federal and Natural Head, while they were yet not born, but when Adam sinned, they inherited being sinners and the corresponding nature and death !
But when Christ, the Second Adam on their behalf fulfilled the Law of God, and cleansed them from their sins by His Blood, they were actually Justified thereby, simply because the sentence of God was actually inflicted upon Him on their stead, hence all their sins were put away, as in Daniel its written Dan 9:24
24 Seventy weeks are determined upon thy people and upon thy holy city, to finish the transgression, and to make an end of sins, and to make reconciliation for iniquity, and to bring in everlasting righteousness, and to seal up the vision and prophecy, and to anoint the most Holy.
As David knew Ps 103 :12
12 As far as the east is from the west, so far hath he removed our transgressions from us.= Justification !
By His Obedience for them, the law was Satisfied in FULL, and to confirm it, He was raised for their Justification or because of it Rom 4:25
25 Who was delivered for our offences, and was raised again for our justification.
Which confirms the Truth that they were Justifed by His Blood alone Rom 5:9
9 Much more then, being now justified/acquitted by his blood, we shall be saved from wrath through him.
So, Justification of this sort is not the result or consequences of ones faith, as an act of the creature, but soley a consequence of the Death of Christ, or His Blood, and God as Judge, adjudged all for whom Christ died unto Life, hence Rom 5:18
18 Therefore 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.
Its a Free Gift given by imputation without faith Rom 5:16
16 And 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.
