21st Sunday in Ordinary Time, Year A: 2nd Reading

Romans 11:33-36

Oh, the depth of the riches and wisdom and knowledge of God!
How inscrutable are his judgments and how unsearchable his ways!
   For who has known the mind of the Lord
      or who has been his counselor?
   Or who has given the Lord anything
      that he may be repaid?
For from him and through him and for him are all things.
To him be glory forever. Amen.
