Most conceive of sin in terms of failing to do what is mandated, and Paul certainly agrees. Fundamentally, however, sin exists when people fail to thank and glorify God (Rom. 1:21). The root sin consists in worshipping and serving the creature rather than the creator (Rom. 1:25). All the discrete acts of sin, are a consequence of failing to honor and give thanks to God (Rom. 1:24, 26, 28). Paul indicts his fellow Jews as sinners because their actions have caused unbelievers to revile God's name (Rom. 2:24). The behavior of the Jews is heinous because it casts a stain upon God's name. The sins recorded in Rom 3:10-18 culminate with the rationale behind them all: the failure to fear God (Rom. 3:18). Schreiner, New Testament Theology, p. 144-145.
