[A speaker at] our stake conference ... told the story of losing her daughter. She experienced immense grief and anger at God who would allow this. She said she was given a dream about five days after her daughter's passing.We should never think, "Oh, it's just a prayer. It's not doing much." What if it is? What if it is doing more than you think?
She was hanging white knuckle over the edge of a cliff with a black void below. She was terrified of falling, but her hands were cut and fatigued, and she was afraid of losing her grip. In her dream she got the impression to let go. This seemed impossible to her because the void below was so dark. She was terrified, but again and again she was impressed to let go, and finally she trusted that feeling and released.
As she was falling, she saw a net of light below her. She could tell it was going to give her a soft safe landing. When she hit the net, she felt wrapped in love and warmth. Then she examined the net and what she saw surprised her. She noticed that there were people at the ends of the net, and that the weave of it was made from light that streamed from them.
She was told in the dream that the strands of the net were made up of the prayers they had offered on her behalf. She saw people close to her who loved her, and they had the brightest and the biggest strands, but she also noticed there were hundreds of people she didn't recognize. She was told that the people she didn't recognize were all the people who had heard what had happened and offered prayers from afar. She closed with the message that no prayer is ever wasted.
