Why is the prophecy about Jerusalem still valid today?
The prophecy about Jerusalem remains valid today because the Gentile powers still exercise basic influence over Jerusalem and the nation of Israel, keeping them under their thumb. Though they do not directly control the city, they still call the shots. This situation will end when Christ returns.
Les explains that the prophecy remains valid because the Gentiles have been overlording Jerusalem for centuries. Even though they are not per se controlling Jerusalem today, it is the next thing to it; the Gentile powers still call the shots and hold the little nation of Israel under their thumb. For all practical purposes, the prophecy is still very valid, and Jerusalem and Israel remain under the basic influence of the Gentile powers. That condition will end when Christ returns. The related prophecy of Israel's spiritual blindness is also not permanent; it will end after the church has been completed.
