What happens to our prayers?

I wonder what happens to our prayers - how they get sorted, who sorts them , what kind of filing system, how they are retrieved in time for execution, what determines when they are executed, what determines whether they are kept in view, put away or pulled up for attention. Whatever it is - God must use the most super sophisticated database, CRM system or whatever to handle all those requests from good and not so good people. (Yeah, even not so good people pray and get their prayers answered  - sometimes). There are some things we will never know  while on our journey here on earth - how God sorts all this out must be one of them. Whatever the answer, it will be God just being God, doing the things that only he can.

The last part of Solomon's prayer when he dedicated the temple (see 1 Kings 8:59) was that his prayers would be always right there before God, day and night, so that God would do what was right for him (Solomon) to guarantee justice for the people of Israel day after day after day. 
So maybe it is not so important what system God employs to manage our prayers  - the key thing is that he allows our prayers to be constantly before him, day and night, such that his will is done in our lives.
