Romans 11:31-35

so these also now have been disobedient, that because of the mercy shown to you they also may now be shown mercy.

For God has shut up all in disobedience, so that He may show mercy to all.

Oh, the depth of the riches, both of the wisdom and knowledge of God! How unsearchable are His judgments and unfathomable His ways!

For who has known the mind of the Lord, or who became His counselor?

Or who has first given to Him, that it would be paid back to him?
