Did the Egyptians and Assyrians (Syrians) ever believe in God?


In that day there will be a highway from Egypt to Assyria. The Assyrians will go to Egypt and the Egyptians to Assyria. The Egyptians and Assyrians will worship together. In that day Israel will be the third, along with Egypt and Assyria, a blessing on the earth. The Lord Almighty will bless them, saying, “Blessed be Egypt my people, Assyria my handiwork, and Israel my inheritance.” Isaiah 19:23-25
            Today there are Christians living in both nations.  While they are predominantly Muslim, many vibrant Christian communities have existed in those two nations.
