Evangelicals have long been influenced by dispensationalism, a theology that promotes a literal reading of biblical prophecy. Many dispensationalists believe Israelites’ return to the Holy Lands is a requirement for the Second Coming of Jesus. When Israeli troops captured the Old City of Jerusalem in June 1967, some saw it as a sign that Jesus was coming. However, dispensational teaching has been waning in mainstream evangelical circles, even as support for a state of Israel has remained strong.
