Romans 11:33 Oh, the depth of the riches of the wisdom and knowledge of God! How unsearchable his judgments, and his paths beyond tracing out! 34 "Who has known the mind of the Lord? Or who has been his counselor?" 35 "Who has ever given to God, that God should repay him?" 36 For from him and through him and to him are all things. To him be the glory forever! Amen.
