The The book of Romans is the most comprehensive book of the Gospel in the entire Bible. It forms the basis of true Christianity. How can unrighteous man be reconciled to God? That has been a question over the ages: "It may be that deity may forgive sin, but I do not know how." (Socrates, 500 B.C.) How can a just God forgive sin without compromising His own righteousness? How can the unjust be declared righteous? Romans 2:1-16 is an expansion of the principle found in 1:18. "For the wrath of God is revealed from heaven against all unrighteousness of men who suppress the truth in unrighteousness...." Then, Paul describes the path of depravity societies follow when they "suppress the truth" (1:19-32). Sodom's depravity was caused by her suppression of the truth.
