Romans 2:29 English Standard Version (ESV)
29 But a Jew is one inwardly, and circumcision is a matter of the heart, by the Spirit, not by the letter. His praise is not from man but from God.
Romans 3:1-20 English Standard Version (ESV)
God's Righteousness Upheld
3 Then what advantage has the Jew? Or what is the value of circumcision? 2 Much in every way. To begin with, the Jews were entrusted with the oracles of God. 3 What if some were unfaithful? Does their faithlessness nullify the faithfulness of God? 4 By no means! Let God be true though every one were a liar, as it is written,
“That you may be justified in your words,
5 But if our unrighteousness serves to show the righteousness of God, what shall we say? That God is unrighteous to inflict wrath on us? (I speak in a human way.) 6 By no means! For then how could God judge the world? 7 But if through my lie God's truth abounds to his glory, why am I still being condemned as a sinner? 8 And why not do evil that good may come?—as some people slanderously charge us with saying. Their condemnation is just.
No One Is Righteous
“None is righteous, no, not one;
19 Now we know that whatever the law says it speaks to those who are under the law, so that every mouth may be stopped, and the whole world may be held accountable to God. 20 For by works of the law no human being[c] will be justified in his sight, since through the law comes knowledge of sin.
Romans 5:12-21 English Standard Version (ESV)
Death in Adam, Life in Christ
12 Therefore, just as sin came into the world through one man, and death through sin, and so death spread to all men[a] because all sinned— 13 for sin indeed was in the world before the law was given, but sin is not counted where there is no law. 14 Yet death reigned from Adam to Moses, even over those whose sinning was not like the transgression of Adam, who was a type of the one who was to come.
15 But the free gift is not like the trespass. For if many died through one man's trespass, much more have the grace of God and the free gift by the grace of that one man Jesus Christ abounded for many. 16 And the free gift is not like the result of that one man's sin. For the judgment following one trespass brought condemnation, but the free gift following many trespasses brought justification. 17 For if, because of one man's trespass, death reigned through that one man, much more will those who receive the abundance of grace and the free gift of righteousness reign in life through the one man Jesus Christ.
18 Therefore, as one trespass[b] led to condemnation for all men, so one act of righteousness[c] leads to justification and life for all men. 19 For as by the one man's disobedience the many were made sinners, so by the one man's obedience the many will be made righteous. 20 Now the law came in to increase the trespass, but where sin increased, grace abounded all the more, 21 so that, as sin reigned in death, grace also might reign through righteousness leading to eternal life through Jesus Christ our Lord.
Titus 3:5 English Standard Version (ESV)
5 he saved us, not because of works done by us in righteousness, but according to his own mercy, by the washing of regeneration and renewal of the Holy Spirit,
