Pray for something is the ultimate act of mental masturbation. If you get what you wanted, aha! God is good! If you don't get what you want, it's because God has other plans. So God hears your prayers and then decides to intercede at his discretion, though presumably he also intercedes in our affairs to time to time without the nudging of prayer.
In effect, you're praying for God to do something and the act of prayer has no impact on it whatsoever. Unless you think you're calling god's attention to something he otherwise wouldn't have noticed. He's sitting up there saying "damn, I was super focused on the middle east bruh, thanks for the heads up on the fact that this dude over in the US ain't christian and is lookin' for a conversion. I'll get right on it. Or won't. Whatever is in my plan."
