Will Prayer Work?

Does someone's will for another to live and be happy make it more likely God will help them? 

I considered how God normally allows free will, but if an individual is willing for God’s will, it allows God to influence their thoughts and decisions, in a post from a few yrs ago; Willing Gods Will. But if the proposed function of this method is that God influences only the thoughts and actions of the person praying, then how can God help others as a result of an individual praying for those others?

It seems likely there are 2 potential aspects to this; God using the individual praying to help the other, or God being more likely to help the other based on desire of more people (who follow and request to God).

The 1st aspect would require the individual that is praying, to have some capable affect on the other whom they are praying for. This would include a lot of scenarios where someone is praying for family, a friend, a loved one, or anybody within their life that they can at least communicate or interact with. A simple example could be Bob prays for God to help his friend Jane, then later God influences Bob to mention to Jane a youtube video he watched about mental health, so Jane watches the video, and gains insight on how to improve her mental health. Or if Bob prayed for a random homeless person on the street he saw, 3 months later, he might be influenced by God to donate $50 to a charity helping homeless people, and that $50 might save that person's life by providing just enough warmth from a donated sleeping bag from the charity, that the same homeless person survives through a few nights of -20C. Bob wouldn't even know that he saved that person's life, but if it wasn't for that donation, the homeless person would have died of hypothermia. God can influence someone to save others that they pray for, even if the 1 that prayed doesn't even realize God used them to save that person. 

The 2nd aspect would be, perhaps God makes changes in this world and causes influences, based on how much collective will there is from people that ask God to help another. This would require zero interaction from the individual praying, with the person that God is helping. It seems likely God would not interfere with the free will of the person being helped, unless that person also asks God for help, based on my theory from about 6 yrs ago; Control to Free, Allowance Degree. 

God could also help someone that doesnt ask for Gods influence on their free will (such as an atheist), if it is making a change in their life not for the purpose of altering their will, but for another purpose, such as helping them have less struggles in life. The purpose of Gods alteration in this world is what's relevant in order to not alter free will, by disregarding his all knowing awareness that anything will influence someone, but still alter circumstances which simply has a side effect of influencing someone's perspective.

Now comes the question; why would God only help someone based on more quantity of collective will, rather than less? This may come down to Gods all knowing perspective, that even though we desire many things, it may not be that relevant. This may sound cold, but God may know that if someone dies, it may not be that significant. That person will either go to Heaven (whatever that may be), or cease to exist (which is what I believe Hell is in a simplified explanation). We may think that continuing to exist as long as possible for the most people possible is best, but we may very well be wrong. For a simple example, someone might live a decent life then become ill and pray to survive, but if their continuing to live is not relevant to others, God could still let them die and go to heaven or cease to exist. On the other hand, if many people will have negative mental health as a result of someone dying that they care about, that could be more significant. Perhaps God is more likely to help someone, if it will improve life for more people already existing. 

So it seems, a simpler way for God to help another that an individual is praying for, is to influence the will of the one praying, to help the other. Whereas another method, could be for God to help that person being prayed for using other methods (without altering free will of that person), and could depend on the quantity of peoples Will for Prayer to Work.
