“This is what Cyrus king of Persia says:

“‘The Lord, the God of heaven, has given me all the kingdoms of the earth and he has appointed me to build a temple for him at Jerusalem in Judah. Ezra 1:2

            By reading Ezra, it seems King Cyrus was “a believer.”  The prophecy from Isaiah (44:28-45:1) clearly announced Cyrus as the future king 100 years before his reign.  Cyrus was certainly amazed by this so he allowed the Jews to return to Jerusalem to rebuild the temple.  Now, did he fully believe in God and God alone?  Not clear. Back then, people believed in many gods and while this God may have been first on the list, it’s unclear if Cyrus believed in Him exclusively.
