Big Idea: Unlike the Mosaic covenant, based on obeying the Torah, the Abrahamic covenant is based on faith. Abraham becomes Paul’s star witness that justification is by faith alone. Paul marshals five arguments to refute the commonly held view that Abraham was justified by his good works: theological (4:1–5), hermeneutical (4:6–8), historical (4:9–12), logical (4:13–17a), and experiential (4:17b–25).

Understanding the Text

The general context of Romans 4 is that it continues the discussion of 3:27–31: the latter states that justification is by faith, while the former illustrates that principle from the life of Abraham. We may correlate these two passages in this way:

1. Justification is by faith (3:27–28; 4:1–8)

2. Justification by faith is for Jews and Gentiles (3:29–30; 4:9–17)
