Did being part of Israel and resting on Abraham's root and fatness automatically make every Jew a believer?

Les explains that although Israel was resting on the root and fatness of the man of faith Abraham, that did not automatically make every Jew a believer—most of them were not. The same principle applies to the Gentile nations now in a place of privilege and blessing, with an opportunity to hear the Gospel and be saved, but that does not mean every Gentile will be saved. Every Gentile has opportunity and will be held responsible at the great white throne, unable to say they never had a chance. God says they rested on the root and fatness of Abraham and had as much opportunity as the covenant people did in the past, but they refused it. Les stresses that when Christ died, He took care of all the sins of the world; every human being has already been declared reconciled and pardoned so far as God is concerned, but until they appropriate it with the kind of faith Abraham had, it is all for nothing. God does not look for someone who knows the Bible from cover to cover or for a primary example of holy living before He can save.
