Romans 4:14

4:14 For if they become heirs by the law, faith is empty and the promise is nullified. ¹ 

Romans 4:13

4:13 For the promise ²  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.

[4:14]  ¹ tn Grk “rendered inoperative.”

[4:13]  ² 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).
