Time-Sensitive Prayers

Obligatory poster for a discussion on time travel... check.

     A while back some Chinese dudes informed us that it is not possible to travel back in time; the math doesn't add up. According to them, it might be possible to go forwards in time, but definitely not backwards (the article I link seems to think differently). I have known this for a long time, though, by this simple logic: If it was possible to travel back in time, then someone would have traveled back in time already. We'd know. He'd show up and say "Hey guys! It's possible! I did it! I traveled as far back in time as I felt safe, just so I could tell you that, hey! It's possible! It turns out all you have to do is have two video cameras recording each other as they record each other, and maybe a solar flare or something! Don't let McDonald's do that pink sludge thing they did-or-will-do for a while!!"
     I understand that logic isn't foolproof, but I think it's pretty close. I do have this one nagging question, though:

     Can prayer travel back in time?

     Do you ever tell someone you'll pray for them, and then forget about it? I have done this several times. One time I had a friend going in for surgery. I told him I'd pray for him during the surgery. I did not. I was probably doing something important like saving Princess Peach or not grading papers at the time. When I remembered that my friend was having surgery, it was like 4 hours after his surgery. I panicked. What do I do?
     Well, I prayed for him. "Dear God I hope his surgery went well."
     Then I thought about that prayer. "Dear God I hope his surgery went well." Besides the fact that it was pretty thin and almost selfish, it had one big problem: It was past tense. I was praying for something that already happened, hoping it happened in a certain way. Was that remotely valid? Did it accomplish anything? Was God laughing at me?
     I guess when I see someone who just came back from vacation, I say "I hope the weather was nice" or "I hope you had a good time." Those are sincere feelings and expressions. But at the same time, I am not trying to impact or change anything about their trip, I'm just expressing that I am pulling for them. Whereas, when I pray for someone's surgery, or job interview, or, I dunno, root canal, to go well, I believe at some level that prayer can actually make a difference in the events that unfold. That is fundamentally different from hoping that the sun was out yesterday.

     So I continued to think about that specific prayer, and prayer in general. Prayer is weird and I don't really get it. If I ask for something, often, and for the right reasons, in the right way, I might get what I ask for? If praying about something causes that thing to happen - and let's pretend that if I hadn't prayed for that thing than it wouldn't have happened - does that mean that prayer can change God's mind? Can God change his mind? Are there things of less consequence that God can decide on at the moment, while others are pretty set in stone?

     (In my opinion, for those last three questions: yes, yes and yes)

     So, say that Joe had a successful surgery. It was successful because so many wonderful, handsome people like myself were praying for him. Except I prayed for him after the fact. But God knew that I would pray for him, so Joe met his prayer quota. So God had the surgery go well at the last second. Whew! Good thing I still prayed even though I thought it was too late, huh!
     No, not a good thing. If I were to pray, today, that 9-11 never happened, it would still have happened. Or if I were to pray that I had never dislocated my shoulder, to grab a much smaller and more reasonable example, it still would have happened. In effect (while dealing with this "Joe" hypothetical), me praying for Joe's surgery didn't change the outcome of his surgery, the outcome of Joe's surgery dictated that I would pray for his surgery!! Don't you see! If God were to make a decision, based on a prayer that I had yet to make, He was really forcing me down a path that I would pray my prayers! What!? No free will!? I don't like that.
     Now, maybe I would have prayed anyways, and sure He could have known that, and thus counted the prayers for that surgery throughout time, but then shouldn't we just devote ourselves to praying for all things past, present, future, but especially in the past?
     What happens if I pray "God I pray I don't pray this prayer." ??

     Conclusion: My prayers cannot go back in time.

     That is okay, because I think the essence of prayer is the heart, and God knows my heart was with Joe, at some pathetically incompetent and selfish level. So even though I didn't pray for his surgery, God might have counted it anyways. Or He might not have cared.

     For what it's worth, I don't think God is looking for a prayer quota, or the right words or conditions for Him to agree to things we ask for. I think it's primarily a method for getting us to talk with Him. I think He just likes having us invite Him in our life. Like when my parents allowed me to be dead broke and starving hungry throughout college; they knew it would bring me home to ask for food and eat dinner, and they were still at point that they liked having me around. (They didn't think I was aware of this sordid little plot but I was.)

     So we cannot go back in time, and our prayers probably can't either. This is undoubtedly a good thing.

    Also, for what it's worth (FWIW as the kids say): I now, whenever I tell someone I will pray for them, pray for them right then. Like, as we are talking I think "Dear God I pray for that thing I just said I'd pray for."
    On a related note, I am not as good of a prarer as I used to be. (Isn't it weird how sometimes we say "pray-yer" and sometimes we say "prare?") So, I guess it's not surprising that I have to resort to praying for someone immediately, and in such a wanting fashion as "I pray for what I just said," but I'll get it back.
