Why was there constant satanic attack against the nation of Israel throughout its history?
Satan attacked Israel because he understood the Abrahamic covenant was the vehicle God would use to bring about the seed of the woman. If Satan could destroy Israel, God's whole program would fall apart; therefore he continually sought to destroy the nation to thwart God's plan.
Les explains that when the Abrahamic covenant was given to Abraham, Satan understood that this was now the vehicle God was going to use to bring about the seed of the woman. So Satan turned on the nation of Israel. All the way up through Israel's history, Les says, there was that satanic attack and the apparent desire to destroy the nation of Israel. The reason was that if Satan could destroy Israel, then God's whole program would fall apart. Les also notes the same pattern as Christianity begins: Satan does everything in his power to disrupt and destroy it in order to thwart the very program of God.
