Romans 11:32

‘For God has shut up all to disobedience, that he might have mercy on all.'

The section now ends with an emphasis on the primary theme, the salvation of all, both Jew and Gentile. For God's purpose in shutting up to disobedience both Jews and Gentiles (Romans 1:18 to Romans 3:20; note especially ‘God gave them up to'), is so that He might eventually be in a position to have mercy on all (i.e. ‘all' meaning either ‘all who will accept it by believing in the Messiah' or ‘all' in the sense of it being inclusive of both Jews and Gentiles). That is His hope. God is not willing that any should perish, but that all should come to repentance (2 Peter 3:9). But, of course, it requires repentance and belief in the Messiah, and that is what is lacking by many.
