What is Justification ?
One writer wrote and I quote:
Justification is an act of God's Sovereign pleasure constituting persons Righteous in the Righteousness of Another and eternally promising to the Lord Redeemer, a discharge to them upon his engagement to perform Covenant conditions perfectly for them. This sovereign Will and Compact of God that unalterably fixes the end, fixes the means conducing thereunto; and this is one of the principal means, that they should of themselves lose their own personal righteousness in Adam their Head, so that they might be alone completely Righteous in the Righteousness of the Redeemer. So far as they are to be understood to have a Representative being in their Everlasting Head, so far as considered in Him they were never otherwise than righteous. Richard Davis {Vindication of the Doctrine of Justification and Union before Faith, 1698.}
Now Two Points of note here. That is all the conditions for Justification before God, hath been fulfilled by Christ, for each Person He knew and died for Isa 53:11
11 He shall see of the travail of his soul, and shall be satisfied:
by his knowledge shall my righteous servant justify many;[Why?]
for he shall bear their iniquities.
It was also said of Old of Him to them I have given thee a Covenant unto the People/ Gentiles Isa 42:6-7
6 I the Lord have called thee in righteousness, and will hold thine hand, and will keep thee, and
give thee for a covenant of the people, for a light of the Gentiles;
7 To open the blind eyes, to bring out the prisoners from the prison, and them that sit in darkness out of the prison house.
This scripture passage informs us a Mystery, that some Gentiles were partakers of the Covenant's of Promise made to Israel Eph 2:11-12
11 Wherefore remember, that ye being in time past Gentiles in the flesh, who are called Uncircumcision by that which is called the Circumcision in the flesh made by hands;
12 That at that time ye were without Christ, being aliens from the commonwealth of Israel,
and strangers from the covenants of promise, having no hope, and without God in the world:
13 But now in Christ Jesus ye who sometimes were far off are made nigh by the blood of Christ. Which Blood is that of the New Covenant Matt 26:28
Isa 42:6 is such Covenant Promise to Israel
Also this Covenant is the Everlasting Covenant, known in time as the New Covenant.
Secondly ,It should not be ignored that the blessed effects of the Covenant, which Christ fulfilled, that these effects are made good to the Heirs of the Covenant, not for their sakes primarily, but for the sake of Him who fulfilled all the conditions of the Covenant, on their behalf, Christ ! For instance, forgiveness of all their sins [Justification] is for HIS SAKE as stated here 1 Jn 2:12
12 I write unto you, little children,
because your sins are forgiven you for his name's sake.
This is a bullet to the head to all conditionalist, who falsely teach one is forgiven upon conditions, such as faith or repentance, thats not Truth, they are forgiven for His Names Sake. More scripture to confirm this point Eph 4:32
32 And be ye kind one to another, tenderhearted, forgiving one another,
even as God for Christ's sake hath forgiven you.74
And since Christ is also God it reads Isa 43:25
25 I, even I, am he that blotteth out thy transgressions
for mine own sake, and will not remember thy sins.
Thats remission of sins also. Sins can never be charged to anyone Christ died for as a matter of condemnation, that is why forgiveness of sins is also a branch of Justification !
This should stop the mouth's of those false teachers who conditions forgiveness or Justification before God on the sake of mens performances, such as Faith or Repentance!
