What the Almighty God has done no power in heaven or on earth can undo it. King Artaxerxes under the impartation of divine love of God did send Nehemiah to rebuild the broken walls of Jerusalem. He backed his authority with fund and ‘visa’ to be able to have free passage through other territories. On arrival there was ready opposition that tried to disturb and get the project un-executable in the persons of Sanballat the Horonite, Tobiah the Ammonite as well as Geshem the Arab. Neh. 2 : 1-20 (NKJV). These people were so pissed off that they jeered at and mocked the Jews. They even went to the extent of putting up petition against the Jews with trump up allegation of possible plan to rebel against the King. They further planned to attack the builders who armed themselves in expectation. They never did because the Jews armed themselves spiritually and physically. Neh. Chs 3 & 4 (NKJV)

As it was in the days of Nehemiah, so it is now and would probably continue to be. The good news is: “but those who know their God shall be strong, and carry out great exploits”. Daniel 11: 32b (NKJV)
