"If her parents and she were so strong in their faith as we were told to believe, what does it say about them that they would want to keep their daughter in that state for a few more years at most instead of standing in Heaven?"
As a matter of fact, most people who are very strong in their faith refrain from sending those who suffer on earth on that quick ticket to heaven. Our faith teaches us that life's journey is not easy for anyone. To be faithful is to know God's work in your life and His home is the end of the journey. We don't cut short the journey for earthly reasons.
We don't cut short the journey for earthly reasons.
And we don't extend it for others for self serving reasons either.
