Romans 11:31-35

Even so have these also now not believed, that through your mercy they also may obtain mercy.

For God hath concluded them all in unbelief, that he might have mercy upon all.

O the depth of the riches both of the wisdom and knowledge of God! how unsearchable are his judgments, and his ways past finding out!

For who hath known the mind of the Lord? or who hath been his counsellor?

Or who hath first given to him, and it shall be recompensed unto him again?
