In Revelation 12, John saw the woman representing God’s people the church, go into the wilderness.
Later in Revelation, an angel took John to that wilderness and he saw the woman and she had changed radically.
John knew this woman, and marveled that she had so changed, even into a harlot.
“But the angel said to me, ‘Why did you marvel? I will tell you the mystery of the woman and of the beast that carries her, which has the seven heads and the ten horns’” (Revelation 17:7).
The woman sat upon the hills of Rome, and became a world-dominating power, and history shows just how the church had changed, and became something that the Lord never wanted her to be.
