The Nature of Sin

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.
