So you’re saying that God should have cancelled His plans because a dude made a stupid vow?

The girl also didn’t seem to protest too much. In fact, she appeared to encourage him. She asked for two weeks up a mountain. It would have been ample time to run away. She didn’t.

Judges 11:36-40

And she said to him, “My father, you have opened your mouth to the Lord; do to me according to what has gone out of your mouth, now that the Lord has avenged you on your enemies, on the Ammonites.” So she said to her father, “Let this thing be done for me: leave me alone two months, that I may go up and down on the mountains and weep for my virginity, I and my companions.” So he said, “Go.” Then he sent her away for two months, and she departed, she and her companions, and wept for her virginity on the mountains. And at the end of two months, she returned to her father, who did with her according to his vow that he had made. She had never known a man, and it became a custom in Israel that the daughters of Israel went year by year to lament the daughter of Jephthah the Gileadite four days in the year.

If you were given an eternity in paradise, why would you waste it thinking about one event back on earth? Some people die worse deaths. And why would you be pissed at God for not making your crappy life a thousand years ago slightly less crappy? You don’t have trauma in Heaven.

Revelation 21:3-4

And I heard a loud voice from the throne saying, “Behold, the dwelling place of God is with man. He will dwell with them, and they will be his people, and God himself will be with them as their God. He will wipe away every tear from their eyes, and death shall be no more, neither shall there be mourning, nor crying, nor pain anymore, for the former things have passed away.”

His daughter didn’t even worry about dying that much- she was more upset that she didn’t have the chance to have offspring. Even she knew that eternity was better than what she had here.
