1. The Cross Declares the Word of God - sola scriptura (scripture alone)
The Bible is the only authoritative Word of God, though traditions; counsels; creeds; and catechisms have their place, they are not inspired writing. Only Scripture is absolutely sufficient for all matters of life and godliness (2 Peter 1:3-4). It is both perspicuous and self-interpreting (Psalm 19:7-9; 2 Tim. 3:16-17). It is forever settled in heaven (Psalm 119:89); more important than our daily food (Job 23:10-12); to be treasured above earthly riches and more desired than this world's sweetest delicacies (Psalm 19:10-11). It is a lamp unto our feet and a light to our path (Psalm 119:105). We are to hide it in our hearts so we wll not sin against Him (Psalm 119:11). How can a young man keep his way pure? By taking heed according to God's Word (Psalm 119:9). It is inerrant, infallible; and the Lord Himself has exalted His Word even above His name (Psalm 138:2).
It is THIS Word that the Apostle begins to unfold a theology of the cross. And he begins by first saying that the cross declares the Word of God.
3.21 "But now…"
That is - at this present time (Roms. 3:26, 5:9); at this very strategic moment in the history of redemption salvation has come. It is what the Apostle calls in Gal. 4:4 "the fulness of time." And for what purpose? That the "righteousness from God has been revealed." This righteousness is realized and authenticated in the life of the believer "apart from the law." Now this means that it was not and cannot be earned by men's obedience to God's law. Law-keeping is an effort in futility; for salvation and acceptance by God through obedience to the law requires a perfect obedience--which sinful man is completely incapable of doing. If we break one part of the law, we break the whole of the law (James 2:10) So the perfect righteousness of God is obtained "apart from the works of the law." (Roms. 3:28, 4:6-8, Gal.2:16, 21; 3:10-13; Eph. 2:9; Phil. 3:9; 2 Tim. 1:9; Titus 3:5).
Is Paul presenting a new doctrine here - something never heard of before? No. He is speaking about "a righteousness attested by the law and the prophets." Paul already referred to Hab. 2:4 in Romans 1:17 "Behold, as for the proud one, His soul is not right within him; But the righteous will live by his faith."
So the cross confirmed and declared the Word of God in Christ fulfilling the law and all righteousness in His sinless life and perfect, once for all sacrifice on the cross (see Psalm 22).
For example: "Now He [Jesus] said to them, 'These are My words which I spoke to you while I was still with you, that all things which are written about Me in the Law of Moses and the Prophets and the Psalms must be fulfilled.'" (Luke 24:44).
Paul must have had in mind some other passages as well: I.e. Gen. 15:6 - "Then he believed in the LORD; and He reckoned it to him as righteousness." Psalm 32:1-2 - "How blessed is he whose transgression is forgiven, Whose sin is covered! 2 How blessed is the man to whom the LORD does not impute iniquity, And in whose spirit there is no deceit!" (see also Roms. 4:3, 7-8).
Two Kinds of Righteousness
The righteousness mentioned here in vs. 21-22 is not the judging righteousness as mentioned in Romans 3:5. This is the saving righteousness of God; this is the gospel which reveals God's saving righteousness apart from the Law and is obtained through faith. How? Again, the Lord Jesus Christ fulfilled the demands of the law and all righteousness in His sinless life; and its penalty and requirements in His perfect sacrifice (His active and passive obedience) and our justification was secured by His resurrection (Rom. 4:25).
The Lord also declared the Word of God after His bodily resurrection from the dead. Luke 24:24-27 says, "And some of those who were with us went to the tomb and found it just exactly as the women also had said; but Him they did not see." 25 And He said to them, "O foolish men and slow of heart to believe in all that the prophets have spoken! 26 "Was it not necessary for the Christ to suffer these things and to enter into His glory?" 27 And beginning with aMoses and with all the bprophets, He explained to them the things concerning Himself in all the Scriptures."
Also in Luke 24:32 And they said to one another, "Were not our hearts burning within us while He was speaking to us on the road, while He awas explaining the Scriptures to us?"
And again in verses 44-47, "44 Now He said to them, "These are My words which I spoke to you while I was still with you, that all things which are written about Me in the Law of Moses and the Prophets and cthe Psalms must be fulfilled." 45 Then He aopened their minds to understand the Scriptures, 46 and He said to them, "Thus it is written, that the Christ should suffer and rise again from the dead the third day; 47 and that arepentance for forgiveness of sins should be proclaimed in His name to ball the nations, beginning from Jerusalem."
Acts 26:22-23, 27, "And so, having obtained help from God, I stand to this day atestifying both to small and great, stating nothing but what the Prophets and Moses said was going to take place; 23 that the Christ was 3to suffer, and that by reason of His resurrection from the dead He should be the first to proclaim clight both to the Jewish people and to the Gentiles." 27 "King Agrippa, do you believe the Prophets? I know that you do."
1 Corinthians 15:1-4, "Now I make known to you, brethren, the gospel which I preached to you, which also you received, in which also you stand, 2 by which also you are saved, if you hold fast the word which I preached to you, unless you believed in vain. 3 For I delivered to you as of first importance what I also received, that Christ died for our sins caccording to the Scriptures, 4 and that He was buried, and that He was araised on the third day according to the Scriptures."
The declares the Word of God.
2. The Cross Defines Salvation as the Work of God - sola fide (faith alone)Salvation comes through faith alone. It is God's grace-gift to us to believe. We are not saved by works - even works done in righteousness (Titus 3:4-7). All our works are rubbish, dung, worthy only of the manure pile. This is the great reformational truth: faith alone, sola fide. Christianity is absolutely unique in this claim. All other religions promise the hope of heaven by human achievement. Only Christianity promises the hope of heaven by divine accomplishment.
This is the means of grace; salvation comes by grace through faith, and that faith is not of ourselves, but is itself the gift of God (Ephesians 2:8-9). Salvation is by faith alone, in Jesus Christ alone. Neither the church, Popes, Mary, bishops and priests nor any other religious figure can add to the finished work of Jesus Christ. He alone stands as the way, the truth, the life--and no man comes to the Father but through Him (John 14:6). And that is by faith.
As the Apostle Paul said previously in Roms. 1:16-17, "For I am not ashamed of the gospel, for it is the power of God for salvation to everyone who believes, to the Jew first and also to the Greek. 17 For in it the righteousness of God is revealed from faith to faith; as it is written, "But the righteous man shall live by faith."
And here in Galatians 3:11, "Now that no one is justified by the Law before God is evident; for, "The righteous man shall live by faith."
But here in Romans 3:22 he now points out that the object of this faith is the Lord Jesus Christ: "even the righteousness of God through faith in Jesus Christ for all those who believe."
This saving righteousness can only be obtained through faith in the Jesus, in and through Whom the One Triune God reveals Himself (John 1:1, 14, 18; 14:9). This faith is a gift from God (Eph. 2:8-9) and comes from hearing the Word of Christ - the gospel (Roms. 10:17). And it is faith that gives us access to God and relationship with Him (Heb. 11:6).
As the Westminster Confession of Faith clearly states:
