1.    Those whom God effectually calleth, He also freely justifieth: (Rom. 8:30+, Rom. 3:24+) not by infusing righteousness into them, but by pardoning their sins, and by accounting and accepting their persons as righteous; not for any thing wrought in them, or done by them, but for Christ’s sake alone; nor by imputing faith itself, the act of believing, or any other evangelical obedience to them, as their righteousness; but by imputing the obedience and satisfaction of Christ unto them, (Rom. 4:5+8+, 2 Cor. 5:19+,21+, Rom. 3:22+,24+–25,27–28+, Tit. 3:5+,7+, Eph. 1:7+, Jer. 23:6+, 1 Cor. 1:30+31+, Rom. 5:17+19+) they receiving and resting on Him and His righteousness by faith; which faith they have not of themselves, it is the gift of God. (Acts 10:44+, Gal. 2:16+, Phil. 3:9+, Acts 13:38+39+, Eph. 2:7+–8)
2.    Faith, thus receiving and resting on Christ and His righteousness, is the alone instrument of justification: (John 1:12+, Rom. 3:28+, Rom. 5:1+) yet is it not alone in the person justified, but is ever accompanied with all other saving graces, and is no dead faith, but worketh by love. (James 2:17+,22+,26+, Gal. 5:6+)
3.    Christ, by His obedience and death, did fully discharge the debt of all those that are thus justified, and did make a proper, real, and full satisfaction to His Father’s justice in their behalf. (Rom. 5:8+10+,19+, 1 Tim. 2:5+6+, Heb. 10:10+,14+, Dan. 9:24+,26+, Isa. 53:4+–6,10–12+) Yet, in as much as He was given by the Father for them; (Rom. 8:32+) and His obedience and satisfaction accepted in their stead; (2 Cor. 5:21+, Matt. 3:17+, Eph. 5:2+) and both, freely, not for any thing in them; their justification is only of free grace; (Rom. 3:24+, Eph. 1:7+) that both the exact justice, and rich grace of God might be glorified in the justification of sinners. (Rom. 3:26+, Eph. 2:7+)
4.    God did, from all eternity, decree to justify all the elect, (Gal. 3:8+, 1 Pet. 1:2+,19+20+, Rom. 8:30+) and Christ did, in the fulness of time, die for their sins, and rise for their justification: (Gal. 4:4+, 1 Tim. 2:6+, Rom. 4:25+) nevertheless, they are not justified, until the Holy Spirit doth, in due time, actually apply Christ unto them. (Col. 1:21+22+, Gal. 2:16+, Tit. 3:4+–7)
5.    God doth continue to forgive the sins of those that are justified; (Matt. 6:12+, 1 John 1:7+,9+, 1 John 2:1+2+) and, although they can never fall from the state of justification, (Luke 22:32+, John 10:28+, Heb. 10:14+) yet they may, by their sins, fall under God’s fatherly displeasure, and not have the light of His countenance restored unto them, until they humble themselves, confess their sins, beg pardon, and renew their faith and repentance. (Ps. 89:31+33+, Ps. 51:7+12+, Ps. 32:5+, Matt. 26:75+, 1 Cor. 11:30+,32+, Luke 1:20+)
6.    The justification of believers under the old testament was, in all these respects, one and the same with the justification of believers under the new testament. (Gal. 3:9+,13+14+, Rom. 4:22+24+, Heb. 13:8+)



The doctrine of justification is the heart and core of the gospel, the “good news” that God by grace alone justifies sinners through faith alone in Christ alone apart from the works of the law. This centrality of justification by faith alone is evident by the fact that when Paul begins to elucidate the “gospel of God,” declaring that “in the gospel a righteousness from God is revealed, a righteousness that is by faith, from first to last” (Rom. 1:17+; see also Gal. 3:8+), he does so in terms of justification by faith.43 Consequently, great care must be taken in teaching this doctrine lest one wind up declaring “another gospel,” which actually is not a gospel at all. To illustrate, one occasionally hears justification popularly defined as God “looking at me just as if I’d never sinned.” This is an example of a (very) partial truth becoming virtually an untruth, since nothing is said in such a definition concerning the ground of justification or the instrumentality through which justification is obtained. Much more accurately, the Shorter Catechism defines justification as “an act of God’s free grace, wherein he pardoneth all our sins, and accepteth us as righteous in his sight, only for the righteousness of Christ, imputed to us, and received by faith alone” (Question 33).
Thus defined over against Rome’s tragically defective representation,44 justification per se says nothing about the subjective transformation that necessarily begins to occur within the inner life of the Christian through the progressive infusion of grace that commences with the new birth (which subjective transformation Scripture views as progressive sanctification). Rather, justification refers to God’s wholly objective, wholly forensic judgment concerning the sinner’s standing before the law, by which forensic judgment God declares that the sinner is righteous in his sight because of the imputation of his sin to Christ, on which ground he is pardoned, and the imputation of Christ’s perfect obedience to him, on which ground he is constituted righteous before God. In other words, “for the one who does not work, but believes in him45 who justifies the ungodly” (Rom. 4:5+),46 God pardons him of all his sins (Acts 10:43+; Rom. 4:6+7+)47 and constitutes him righteous by imputing or reckoning the righteousness of Christ to him (Rom. 5:1+, 19+; 2 Cor. 5:21+).48 And on the basis of his constituting the ungodly man righteous by his act of imputation, God simultaneously declares the ungodly man to be righteous in his sight. The now-justified ungodly man is then, to employ Luther’s expression, simul iustus et peccator (“simultaneously righteous and sinner”).
The doctrine of justification means then that in God’s sight the ungodly man, now “in Christ,” has perfectly kept the moral law of God, which also means in turn that “in Christ” he has perfectly loved God with all his heart, soul, mind, and strength and his neighbor as himself. It means that saving faith is directed to the doing and dying of Christ alone (solus Christus) and not to the good works or inner experience of the believer. It means that the Christian’s righteousness before God is in heaven at the right hand of God in Jesus Christ and not on earth within the believer. It means that the ground of our justification is the vicarious work of Christ for us, not the gracious work of the Spirit in us. It means that the faith-righteousness of justification is not personal but vicarious, not infused but imputed, not experiential but judicial, not psychological but legal, not our own but a righteousness alien to us and outside of us (iustitia alienum et extra nos), not earned but graciously given (sola gratia) through faith in Christ that is itself a gift of grace. It means also in its declarative character that justification possesses an eschatological dimension, for it amounts to the divine verdict of the Eschaton being brought forward into the present time and rendered here and now concerning the believing sinner. By God’s act of justifying the sinner through faith in Christ, the sinner, as it were, has been brought, “before the time,” to the Final Assize and has already passed successfully through it, having been acquitted of any and all charges brought against him! Justification then, properly conceived, contributes in a decisive way to the Calvinistic doctrine of assurance and the eternal security of the believer. Let us now look in greater detail at some of the specific
