God will use whomever He pleases to accomplish His will. Even those not in His fold, He will use them to bless His people.
Read: Ezra 1:2-4
“This is what King Cyrus of Persia says:
“The Lord, the God of heaven, has given me all the kingdoms of the earth. He has appointed me to build him a Temple at Jerusalem, which is in Judah. 3 Any of you who are his people may go to Jerusalem in Judah to rebuild this Temple of the Lord, the God of Israel, who lives in Jerusalem. And may your God be with you! 4 Wherever this Jewish remnant is found, let their neighbors contribute toward their expenses by giving them silver and gold, supplies for the journey, and livestock, as well as a voluntary offering for the Temple of God in Jerusalem.”
