How big is God?

There are 6 billion people in the world. God will is all mankind to be saved, but everyone has a free will to choose their own destiny. If one million people pray, that is 1/6000 of the population, will God answer every single prayer request. If a million people pray to win the lottery, and God said yes to all, a million people would win $1, because there were a million winners. If two christians pray living in the same area, one wanted rain, because he was growing crops and the other wanted plenty of sunshine because the work he was doing was outdoor work. How would God answer the pray request of both christians?. If a million people pray for a miracle or supernatural healing, will God say yes to every request and so a million people at once gets healed. God has to satifisy millions of prayer requests from christians all over the world. It would be a mighty task to fulfill those requests. God knows every single prayer request, and answer them one by one. God know what our needs are and will provide all our needs, sometimes it might not be the answer we are looking for, but don;t worry because God always provide for us for what is needed.
