Paul brings the section on Israel, chapters 9 - 11, to a climactic close with one of the most beautiful doxologies in the Bible:
Romans 11:33 Oh, the depth of the riches and wisdom and knowledge of God! How unsearchable are his judgments and how fathomless his ways! 11:34 For who has known the mind of the Lord, or who has been his counselor? 11:35 Or who has first given to God, that God needs to repay him? 11:36 For from him and through him and to him are all things. To him be glory forever! Amen.
