I don't know what you should take from it. But I also know that nothing on the face of this earth happens without God knowing about it. Is this her time? Or was her time 15 years ago? We don't know for sure, but I have prayed about it a lot and just asked that God's Will be done, not mine. I'm not going to get into my thoughts on the case because honestly I can see both sides, the side of the parents' grief and the side of a woman finally getting to go home.
But yes, it will work out in the end. No matter what we may believe, God is and always will be in control
"Or was her time 15 years ago?"
No. That is a silly question. God is sovereign and His will is never thwarted by man. If she was meant to die then, she would have died then.
If she dies now, it was God's timing.
