We are the servants of the God of heaven and earth

Ezra 5:1-17
Now Haggai the prophet and Zechariah the prophet,  prophesied to the Jews in Judah and Jerusalem in the name of the God of Israel, who was over them. Then Zerubbabel son of Shealtiel and Joshua son of Jozadak set to work to rebuild the house of God in Jerusalem. And the prophets of God were with them, supporting them.
“Who authorized you to rebuild this temple and to finish it?” They also asked, “What are the names of those who are constructing this building?
But the eye of their God was watching over the elders of the Jews, and they were not stopped until a report could go to Darius and his written reply be received.
Tattenai, governor of Trans-Euphrates, and Shethar-Bozenai and their associates, the officials of Trans-Euphrates, sent to King Darius.
“We are the servants of the God of heaven and earth, and we are rebuilding the temple that was built many years ago, one that a great king of Israel built and finished.
However, in the first year of Cyrus king of Babylon, King Cyrus issued a decree to rebuild this house of God.
Urged on by the prophets Haggai and Zechariah, the people again start building. This time an attempt to get the new king, Darius, to stop it has the opposite effect. Darius checks the court records, and discovers the scroll on which King Cyrus; decree is written. The Jews have official authorization for their Temple, even to the dimensions and materials used.
Why?
The prophet has word of God and he encouraged people of Jew to rebuild house of God.
Who we are, We are servants of the God of heaven and earth.
How?
For I am servant of God so I am humble and raise name of the Lord.
