Paul says that while God reveals Himself through creation, men suppress this truth in unrighteousness and fall into idolatry. He convicts mankind of two particular evils: the refusal to honor God as God and the failure to give thanks to God. In other words, there is another sin that accompanies the primary sin of the fallen human race: in addition to refusing to adore, honor, and worship God, we also refuse to be thankful to God.
