Yes I felt a lot better since. It boosted my faith and sense of His presence in the world. Praying that you will receive peace and comfort about this. You, no we may also pray that her days are prolonged. We have a given lot but according to the Bible days can be shortened by violence or prolonged...
My fears started when my grandpa died. He died pretty abruptly. Heart attack, and he was gone in half an hour. That got into my mind "I can lose people out of nowhere". But from what I've seen on my grandma, who is a believer, she died when it was her time to go. She was holding on mainly for me, after she saw me married her health started deteriorating massively and it would have been a great suffering for her to continue in that health condition. I saw her in a dream while she was still alive, she was standing in a garden and watching, as if she was guarding. And I could tell she was very tired from standing and craved rest, and sun was setting, but she was still watching and guarding. So then I knew, that she was holding onto life still for me, to see me married and that my life was okay. And God allowed her to see it and then after some time she departed. My point being, God is graceful and believers may petition God with such things, and I pray that God will allow your mama to stay here for as many days as possible into ripe old age. Amen, please, lord Jesus.
