Justification by Faith is in two senses, First and foremost Its Justification by the Faith / Faithfulness of Jesus Christ. For its by this Faith alone how The elect obtain Justification before God, by the Blood and obedience of Jesus Christ, for all whom He died in their place and stead..
Rom 5:9,18-19
9 Much more then, being now justified by his blood, we shall be saved from wrath through him.
Note, being Now Justified by His blood, not our Faith + His blood, that's a false Gospel, but by His blood..to whom is this True of ? Not only the roman believers, but to all the election of grace of all time..Thats who Justified by His blood..
18 Therefore as by the offence of one judgment came upon all men[of all time] to condemnation; even so by the righteousness of one the free gift came upon all men [of all time] unto justification of life.
19 For as by one man's disobedience many were made sinners, so by the obedience of one shall many be made righteous.
Again no mention of our Faith as a securing means of Justification unto Life or being made righteous, but solely the obedience and righteousness of One Jesus Christ..
This constitutes the Faith / faithfulness of Jesus Christ. Therefore its written The Faith of Jesus Christ:
Gal 2:16,20
16 Knowing that a man is not justified by the works of the law, but by the faith of Jesus Christ, even we have believed in Jesus Christ, that we might be justified by the faith of Christ, and not by the works of the law: for by the works of the law shall no flesh be justified.
20 I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave himself for me.
In Faithfulness Jesus Christ Loved the elect and gave himself for them.
Then in a secondary sense and premised on the First and foremost, the elect sinner is Justified consciously, by the regenerating work of the Holy Ghost, because of their previous justification by the work of Christ, they now have that revealed to them by God the Holy Ghost through the Gospel. But be careful not to confuse the receiving experientially the status of Justification before God [by the work of Christ] with the experiential aspect of conscience Justification by the work of the Holy Ghost upon and in the already Justified before God sinner.. 1 Cor 6:11
11 And such were some of you: but ye are washed, but ye are sanctified, but ye are justified in the name of the Lord Jesus, and by the Spirit of our God.
Now, though the work of the Holy Ghost is extremely Important and needed for the enjoyment of the work of Christ in the elects behalf, His blessed work should never be on the same level or above the Justifying work of the Son of God upon the cross. to do so leads to heresy and false teaching.
For it was not the Work of the Holy Ghost to die in the place of elect sinners for 1 Cor 15:3
3 For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures;
This scripture teaches Christ died for our [the elect] sins, but not a word about the Holy Ghost dying for the sins of the elect.
Isa 53:6
6 All we like sheep have gone astray; we have turned every one to his own way; and the LORD hath laid on him [Jesus Christ] the iniquity of us all.
Here, the iniquities of the elect were laid upon him [Jesus Christ] and not the Holy Ghost..
Rom 5: 9 declares Having been Justified [declared righteous] by the blood of Jesus Christ, but not a word about being Justified by the work of the Holy Ghost blood..
Finally Jesus states that the Holy Ghost will not speak of Himself [ draw attention to Himself] but should Glorify Him..Jn 16:13-14
13 Howbeit when he, the Spirit of truth, is come, he will guide you into all truth: for he shall not speak of himself; but whatsoever he shall hear, that shall he speak: and he will shew you things to come.
14 He shall glorify me: for he shall receive of mine [My accomplishment], and shall shew it unto you.
He shall receive of the finished accomplished Justification of Gods elect through Jesus Christ and on their behalf, and shew [ reveal] it to them..
To confuse or mix the Two types of Justification, Legal and experiential[conscious] is fatal.
