Romanos 4:15

Rather than bringing blessing, which God promised Abraham, the Law brings wrath because no one can keep the Law perfectly. Whenever there is failure, wrath follows. However without law there can be no violation and therefore no wrath. Moo explained Paul’s logic as follows.

"Violation of law turns ’sin’ into the more serious offense of ’transgression,’ meriting God’s wrath

God gave the law to the Jews

The Jews have transgressed the law (cf. Romans 2:1-29; Romans 3:9-19)

The law brought wrath to the Jews . . .

"Paul, then, is not claiming that there is no ’sin’ where there is no law, but, in almost a ’truism,’ that there is no deliberate disobedience of positive commands where there is no positive command to disobey." [Note: Ibid., pp. 276, 277.]
