Isaiah 28 - 29

Just because one is an inhabitant of Jerusalem, their safety and blessing is not guaranteed.  God promises that He will judge based on personal criteria, and that place of residence is not one of the qualifying parameters.  Those who despise God's word and teaching will be judged.  Yet those who profess to love God while their hearts want nothing to do with Him will also be chastened, as God desires a pure and sincere worship.  In spite of all the promises of punishment and discipline, God will still bring about good to those who love, fear and serve Him.
