Someone commented once about this. I apologize for not remembering who it was. But he or she was talking about their grandfather who had Alzheimer's and how it was like Grandfather was in a boat that was drifting farther and farther from the shore where they stood, disappearing slowly but inexorably into the mist. That is such a lovely, sad, but apt description. I can't stop the boat, I can't clear the mist, I can only stand on the shore and feel lonely and reach out with love but helplessness and grief. It is the same with my sister. She is lost in the mist, and I can't find her. I want to share this grief with her, because she would understand more than anyone. I miss her so much.
Meanwhile, this verse from my older blog post was comforting.
2 Corinthians 4:15-17 All of these things are for your benefit. And as God's grace brings more and more people to Christ, there will be great thanksgiving, and God will receive more and more glory. That is why we never give up. Though our bodies are dying, our spirits are being renewed every day. For our present troubles are quite small and won't last very long. Yet they produce for us an immeasurably great glory that will last forever!
"Immeasurably great glory..." Oh Lord God, may it be so!
