Hosea 2:15

"And I will give her her vineyards from thence, and the valley of Achor for a door of hope; and she shall make answer there, as in the days of her youth, and as in the day when she came up out of the land of Egypt."

"The valley of Achor ..." It was in this place that the sin of Achan involved all of Israel in a disastrous defeat; but, after Achan was put to death, the same place became "a door of hope," leading to a great victory that opened up the entire land of Canaan for Israel. What is the application? The spiritual death and defeat of the old Israel, after they (in the sense of the apostate nation) were formally sentenced to death by the Lord Jesus Christ, that very defeat of the old Israel, became the principal means of winning the new bride of Jehovah, the church of Jesus Christ, composed of the spiritual remnant of the old Israel and also of vast numbers of the whole Gentile world. The apostle Paul himself mentioned this connection between the defeat of Israel and the salvation of the world as follows: "The casting away of them is the reconciling of the world!" (Romans 11:15). Thus the spiritual death and defeat of the secular nation, especially as exhibited to the entire world in the overthrow and destruction of Jerusalem, became a principal proof of the truth of all that Christ had said, removing at the same time any further efforts of the secular Judaism to exterminate Christianity, thus becoming indeed a "door of hope" for all mankind. Failing to understand any of the phenomenal implications of this passage has led to many bizarre and even ridiculous efforts to get rid of the passage. The spiritually blind cannot interpret God's Word.
