Remission/Forgiveness of sins = Justification !
None in false religion today believe that those Christ died for, by His redeeming death alone, that they are all Justified before God, yes even before they believe, and even while they are unbelieving enemies by nature ! This is True because by His death alone for them, they have received in the Court of Heaven before the Throne of God, Remission/Forgiveness of sins, which is also a branch Justification ! Listen to the words of Christ here Matt 26:28
28 For this is my blood of the new testament, which is shed for many for the remission of sins.
The word for here eis means that the shedding of His Blood for that particular many resulted in the remission of their sins, which also means Justification !
There is Salvation resulted in also in the remission of sins, Lk 1:77
77 To give knowledge of salvation unto his people by the remission of their sins,
Yes all their sins, past, present and future have been forgiven because of the shedding of the blood, which also means they are Justified before God, even when they have not been yet Justified before their own consciousness and while they are in unbelief and ignorance !
Jesus Christ was raised from the dead because of our Justification Rom 4:25
25 Who was delivered for our offences, and was raised again for[because of] our justification.
That word Justification, the greek word dikaiōsis means:
I.the act of God declaring men free from guilt and acceptable to him
See that's what Remission of sins means, God declaring men and women free from guilt based upon the blood shed of Christ alone !
The word remission in Matt 26:28 is the greek word aphesis which means:
II. forgiveness or pardon, of sins (letting them go as if they had never been committed), remission of the penalty
And again that equates to Justification:
the act of God declaring men free from guilt
This is not based upon anyone's faith, or repentance or even believing the Gospel, those things have nothing to do with it, but based solely upon the Blood shed of Jesus Christ ! 17
