The car example was a simple one to illustrate my point. The fact that you pray for x, and then x happens, doesn't demonstrate that God/the prayer caused x. The fact that you don't know what else could have caused x, doesnt demonstrate that God/the prayer did it.
You are right about the car example, there is no way to know if God answered the prayer.
In general it is not a good idea to pray for x, but rather to pray for assistance, and let God decide what the outcome will be, because God knows what is best. I always act to try to address the problem I am having, but when there is no more that can be done, I pray like there is no tomorrow, because I know that only God can help me, IF He chooses to. I have been praying for two days, 4 hours yesterday, 4 hours today. I got an answer I was not expecting and I consider it a miracle. It might not last but I live one day at a time and try to accept God's will, whatever that is.
An interesting thing has been happening for the last few years. When I accept God's will, things that never happened before have happened, and they are miracles. I think God knows I am ready to accept whatever His will is so He does not have to test me anymore. In the past, I did not accept God's will and things did not go as I hoped they would. Of course, this is just my theory as to why things happened, I could never prove it, but it has been repetitive so to me that is some evidence.
I am not saying that everything has gone my way, far from it, but somehow I got through the tragedies whereas in the past when I did not turn to God, the same experiences landed me in urgent care on many occasions.
Great, so let's look at an actual example and see what extraordinary evidence there is. What's the last prayer you prayed in which you think God provided what you asked for? And how did he answer?
I do not want to get specific about what I am going through right now, but I have a story I want to share about prayer. A good forum friend of mine had a cat who was 20 years old and that cat was in his last days owing to kidney failure. That cat meant
everything to him and he told me his life would never be the same after that cat passed on. Towards the end when his cat was looking really bad and really suffering he cried out to God for help, even though he was an atheist, because intuitively he knew that was his last option. He made a deal with God that if God answered his desperate prayer, he would never rank on God again, as he had been doing, since he was a regular poster on a Christian forum and my forum ranking on Christian beliefs.
Within minutes of his prayer, the cat's droopy dribbling eyes completely cleared up and the cat got up and went over to the food dish and ate a whole lot of food and drank water. His cat walked normally, jumped up on the bed, whereas before it could barely walk. The cat passed on not long after that, but my friend told my other friend that he planned to keep his part of the bargain. He never ranked on God again, and he said he is no longer an atheist. Interestingly, his friend was so taken by what happened he now also believes in God!
I have not posted to my friend with the cat since because he left my forum. My other friend who lives near him went with him to the animal shelter and he got another cat that was perfect for him, and he has been very happy. I honestly never thought he would recover because I never saw him that depressed. He warned me that after the cat passed on he would not me back to forums because he knew that would change his life. He just did not know it would be for the better.
This story made me think of another story. A few years ago, a poster showed up on a Baha'i forum and I came to find out he had been an atheist but now believes in God. From what he had posted I could tell his faith in God far exceeded mine so I sent him a private post and asked him what happened to him. He then told me his long story. I cannot remember every detail, but I saved it in a Word document to refer back to later. The gist of it is that he had been going through some very difficult times and he was at the end of his rope. While was driving on a country road he cried out to God for help. Almost immediately, his car radio went berserk and he got some kind of communication from God that God had heard his prayer. That man has never been the same since.
I never used to believe these things really happened but that is not the only time I have heard a story like this. Another man I knew from forums who had been an atheist since childhood (both his parents were atheists) wanted to know if God exists so he looked up into the sky and asked for a sign. That night he got his answer.
I am sorry I cannot remember all the details because these things were posted several years ago, but that is the gist. Both these men became faithful believers. They did not join a religion right away, but shortly after they realized that God existed, they started researching religions. I do not know why the man who had the car radio experience ended up on a Baha'i forum, but the other one who looked up into the sky told us the reason he came to a Baha'i forum is because what was revealed to him that night was very similar to what Baha'is believe. That man researched the Baha'i Faith and then the Bible. I lost track of him after that.
I never have supernatural experiences and it is my theory that is because God knows I will believe in Him without them. I really thing that if people sincerely reach out to God, God will give them a sign, but the common thread that runs through all these experiences is that it has to be done in humility.
