6/26/13 V. 7, Because her sins are so many and because they have persisted in them for so long, God will eventually judge her. The sin of bold unfaithfulness to the Lord by following after other gods and blaspheming him is the theme of many OT prophets. The actions of the little horn power in Dan 7:25 and beast in Rev 13:1 and 16:11 are both cross-referenced with this verse.
V. 8, However, not all among apostate Israel have followed after other gods. Among the grape harvest (Rev 14:18-19) there are some good, which God will separate out. He will not destroy the righteous with the wicked. God, who is able to read the heart, will divide the good from the bad, as in Jesus’ parable of separating the good fish from the bad in the net and separating the sheep from the goats. In Mt 24:22 Jesus, speaking of the time of Jacob’s trouble, says that he will cut short those days for the sake of the elect.
V. 9-10, As always, God will have a remnant people that he shall bring through the trials and difficulties. His purpose is to bring from humanity a people whom he will call his own children as heirs to his kingdom. That means that God plans for us to inherit the place he has promised us, which, as we have seen before, is heaven itself. We will dwell with God (Rev 21:3) and rule with him (Rev 1:6, 5:10, 20:6) and we and the whole universe will have rest.
