Romans 1:18-30, Romans 1:31 and Romans 1:32

Romans 1:18-31
Paul begins his exposition of the gospel with the claim that God's nature should be evident to all from his creation. He proceeds to outline the general rejection of God by mankind. He illustrates this depravity by citing the rise of sexual immorality, and homosexual practices in particular. He probably chooses this illustration as one that will be especially distasteful to the Jewish portion of his audience. Rather than focusing on the negative attitude shown towards homosexuality here, though, we should focus on Paul's overall argument, which will eventually suggest that the apostasy of the Jews is far worse than the obvious depravity of their gentile counterparts.
