That is completely false that Jesus came to rescue the Jews, he came to end the Jewish system of things, not save the Jews, and this once saved always saved ideology has no scriptural support what so ever. The scriptures are clear, there are people in this world, and the scriptures mention them as a majority, that are going to be destroyed upon Christ return. A person can find themselves in a position where although once in the favor of Jehovah, go against him, and when they do, Grace is not going to save them. Not everyone living in the world created by Satan, are suddenly going to switch sides and behave themselves when Satan is destroyed. The kingdom of Satan is not going to simply change, from Satan being King, to Jehovah being King, and all other things remain the same. Now Americans as a nation of people think that is already true. No matter how much evil America perpetuates upon this globe, Americans continue to believe that they have God’s support and approval and blessing, nothing could be further from the truth. There are actually people in America, who go to church, claim to be under God’s grace, claim to worship him, and yet at the very same time, place the American flag on their doorsteps, the very symbol of the most evil nation Satan ever created. It is possible to be destroyed by God, when God said, “You positively will die” he meant it. He never once said that you can do anything you want, kill as many people as you care to, commit any sort of immorality that you care to and I will still make sure that you remain alive to perpetuate your evil deeds. Christ was clear when he said that those doing the will of my Father would remain alive. Doing the will of God requires action of some kind, belief alone, is shared even by the demons, and they certainly do not come under grace.
