Following the recent Barack Obama-Benjamin Netanyahu dust up over Israel's current borders, many evangelicals have responded by warning of covenant curses coming upon those nations who don't support Israel's right to the land (with its current boundaries), because Israel is supposedly a "holy land," or because Israel "has a covenant with God."
The political questions surrounding Israel are important and notoriously difficult to answer. Where to draw the borders? Should there be a Palestinian state? Should there be a divided Jerusalem?
But to invoke covenant curses because of an unbiblical notion that the modern nation of Israel is a "holy land" is quite another. In fact, it reveals a serious misunderstanding of redemptive history to do so. Israel is a modern secular nation, like America, China, or the Philippines. Israel does not sit on "holy land." Jesus Christ fulfilled that covenant God made with Israel at Mount Sinai. Furthermore, it was Paul who universalized the land promise from Palestine to include the whole earth (Romans 4:13)
