Roma 4:13

4:13 For the promise ¹  to Abraham or to his descendants that he would inherit the world was not fulfilled through the law, but through the righteousness that comes by faith.

Roma 7:20

7:20 Now if I do what I do not want, it is no longer me doing it but sin that lives in me.

Roma 9:32

9:32 Why not? Because they pursued ²  it not by faith but (as if it were possible) by works. ³  They stumbled over the stumbling stone, ⁴ 

[4:13]  ¹ sn Although a singular noun, the promise is collective and does not refer only to Gen 12:7, but as D. Moo (Romans 1-8 [WEC], 279) points out, refers to multiple aspects of the promise to Abraham: multiplied descendants (Gen 12:2), possession of the land (Gen 13:15-17), and his becoming the vehicle of blessing to all people (Gen 12:13).

[9:32]  ² tn Grk “Why? Because not by faith but as though by works.” The verb (“they pursued [it]”) is to be supplied from the preceding verse for the sake of English style; yet a certain literary power is seen in Paul’s laconic style.

[9:32]  ³ tc Most mss, especially the later ones (א² D Ψ 33 Ï sy), read νόμου (nomou, “of the law”) here, echoing Paul’s usage in Rom 3:20, 28 and elsewhere. The qualifying phrase is lacking in א* A B F G 6 629 630 1739 1881 pc lat co. The longer reading thus is weaker externally and internally, being motivated apparently by a need to clarify.

[9:32]  tn Grk “but as by works.”

[9:32]  ⁴ tn Grk “the stone of stumbling.”
