Romans 11:29-36 NKJV
For the gifts and the calling of God are irrevocable.  For as you were once disobedient to God, yet have now obtained mercy through their disobedience,  even so these also have now been disobedient, that through the mercy shown you they also may obtain mercy.  For God has committed them all to disobedience, that He might have mercy on all.
 Oh, 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 has known the mind of the LORD? Or who has become His counselor?”  “Or who has first given to Him And it shall be repaid to him?”  For of Him and through Him and to Him are all things, to whom be glory forever. Amen.
Matthew 24:14 KJV
And this gospel of the kingdom shall be preached in all the world for a witness unto all nations; and then shall the end come.
