Paul opens his argument for the gospel by revealing the need for it. God is righteous and no descendant of Adam is, due to Adam's disobedience. Thus, Romans 1:18-32 demonstrates the total depravity of man summarized in Romans 3:10, "None is righteous, no, not one." The sad news is that when people reject God, He rejects them and allows their sinful tendencies to play out in three stages: (1) when people refuse the truth about God, He lets them worship false gods. (2) When they worship the creature, God lets them degrade the creature. (3) The degraded creature not only plunge into greater debauchery, but they also take pleasure in those who do what they do, knowing that it is wrong.
