Justified by Grace !
That those Christ died for, are Justified before God, by His redeeming death alone, apart from their faith , their believing, or any Gospel obedience whatsover, and while they are still being ungodly Rom 4:5, it is confirmed by this Truth right here Rom 3:24
24 Being justified freely by his grace through[on the account of] the redemption that is in Christ Jesus:
NOG:
24 They receive God’s approval freely by an act of his kindness through the price Christ Yeshua paid to set us free from sin.
Basically what this means, God accepts all those Christ died for as Righteous, a Gracious Gift, simply on the basis of Christ Paying the ransom.
That's being Justified by Grace, a Free Gift, not offered, not made available, but a Divine Reckoning in the Mind of God for us Rom 8:31-34
31 What shall we then say to these things? If God be for us, who can be against us? 7
32 He that spared not his own Son, but delivered him up for us all, how shall he not with him also freely give us all things?
33 Who shall lay any thing to the charge of God's elect? It is God that justifieth.
34 Who is he that condemneth? It is Christ that died, yea rather, that is risen again, who is even at the right hand of God, who also maketh intercession for us.
God does not lay any charge against them for whom Christ paid the ransom for, and that's Justification for them freely because of the Redemption in Christ Jesus !
The redemption is His Blood payment, as a result of His Offering Himself in their stead and behalf, to satisfy God's Law and Justice against all their sins they sinned against His Law. God has nothing to charge them with, they are totally forgiven through His Blood Matt 26:28
28 For this is my blood of the new testament, which is shed for many for the remission of sins.
Remission of sins is the result of the shedding of the blood ! Remission means:
a sending away, a letting go, a release, pardon, complete forgiveness.
It s a setting free of sin, a Justification, being made free from sin as in Rom 6:7
7 For he that is dead is freed from sin.
That word freed[dikaioō] means :
to render righteous or such he ought to be
2) to show, exhibit, evince, one to be righteous, such as he is and wishes himself to be considered
3) to declare, pronounce, one to be just, righteous, or such as he ought to be
It can read:
for he that hath died is justified from sin.
7 For someone who has died has been cleared from sin.
They died in the Head, the Lord Jesus Christ. They died in Him Representativley in the same way they died representatively in Adam Rom 5:12
12 Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned:
All for whom Christ died, they died with Him, Paul concludes that here 2 Cor 5:14
For the love of Christ constraineth us; because we thus judge, that if one died for all, then were all dead:or
14 For the love of Christ constraineth us; because we thus judge, that one died for all, therefore all died;ASV
So that's why Paul writes Rom 6:7
7 For he that is dead is freed from sin.
Having died [with Christ] they have been Justified from sin !
Eph 1:7
7 In whom we have redemption through his blood, the forgiveness of sins, according to the riches of his grace;
This is actually the same thing Paul writes in Rom 3:24, except He emphasizes forgiveness of sins for Justification or being Justified by His Grace through Redemption.
Eph 1:7 Jesus Christ has given his blood [died] to make us free. He has forgiven us for our wrong ways. We have been put right with God freely because of his great kindness.WEB
Now this Justification by Grace has absolutely nothing to do with anything the benefactors did, thought or said, in fact in regards to them it [Justification] was without cause and it was undeserved It is solely based upon Christ's Death/ Blood shed for them.
That's why Paul says later that Christ was raised again for our Justification Rom 4:25
25 Who was delivered for our offences, and was raised again for our justification.
25 Who was betrayed and put to death because of our misdeeds and was raised to secure our justification (our acquittal), [making our account balance and absolving us from all guilt before God].
Why ? Because of the redemption through His Blood ! So being Justified by His Grace freely through redemption, is not the same as being Justified by Faith, unless we do mean by faith, Christ's Faithfulness in shedding His Blood !
