Your kid wants a telescope. You think it’s an awesome idea, but you also think it’s an awesome idea that he should learn about the value of money, and the value of work, so you say no to that telescope for the time being, however once the kid has mowed enough lawns (or whatever) to have raised enough money, you say yes to the telescope. Your initial “no” is temporary and the potential “yes” is conditonal, does that make sense? Except that communication with God is less fluid and straightforward than it is between you and your kid, so we have to sort of guess what God’s will is by trial and error. It took ages for God to get Sarah a kid, she was well past child-bearing age, yet throughout all these years that she didn’t conceive, people would have probably concluded that life-long sterility was God’s will for Sarah. And even is x is God’s will for me, if I live like the Devil, sin left and right, and do not even so much as pray for x, x ain’t gonna happen. If you take away from what I’ve been saying is that prayer is useless, then you misunderstood and/or I didn’t express myself adequately. Plus we can never figure out God, put him in a box, there is always a great deal of mystery in all of this. If you pray a novena for a thorny situation to resolve itself, if the situation resolves itself indeed, who is to say with 100% assurance that God stepped in somehow, it can always have come from a coincidence. Same with the people of Ninive: God will wipe them out if they remain the same, but will spare them if they don’t remain the same, that’s a conditional “offer”, just like Fatima/Akita is/are, God’s will remains unchanged throughout the whole thing: punish sin if sin continues, or show mercy if sin stops. Perhaps I’m totally off on this, although it would really be a first!
