That's kind of the basis of my question. If God ultimately decides who lives and who dies, regardless of prayer, what purpose does prayer serve? And if prayer does serve a purpose, is God really deciding, or is he allowing humans to decide?
Also - and I don't mean this in any negative way, I'm just making sure I understand your point - are you saying that God decided that your uncle's life was less important than you and your father spending time together, and your uncle's death was a sacrifice to make that happen?
Good questions indeed, we've asked the same questions ourseleves, as well as countless others who share the same experiences.
I'm a believer that God allows life to happen, meaning, birth, death, tragedy, murder, etc... I think God steps in an alters the outcome when when it serves a greater purpose.
The best example is Jesus on the cross. God the Father certainly could have altered the course there or Jesus himself could have stopped the crucifixion at any point. Yet the consequences of his death were far greater than the physical and spiritual pain he experienced.
So in time of hardship, the example of Jesus dying on the cross and suffering for us is a comfort. It makes seeing that loved one pass on that much easier to deal with.
So to answer the question regarding my uncle's sudden death, I think God allows death to happen, but, if we ask for guidance in these difficult times, God can turn it into something good. But the key is that we have to be open to that spiritual communication, otherwise, we can become bitter and blame God for things we do not underdstand.
