there are thing that we must do before HE grants our request. you may not know, or you already know, but you refuse to, like the cancer patient refused to forgive her mother for almost a decade until finally she surrenders and forgave her mother.
"After Job had prayed for his friends, the LORD restored his fortunes and gave him twice as much as he had before."
as I said, what one must do WILL differ because everybody has their own life, circumstances, wrong choices, right choices, weaknesses, strengths, etc. that's why the HELPER, the HOLY SPIRIT will help you to remind you of what you may have forgotten or need to do. this is NOT cruel.
People cant make God do anything? Hezekiah would beg to differ. he CHANGED GOD's death verdict, and had a son, although the son turned out to be evil...
raise your sister from the dead? of course HE can. HE did that to lazarus, although HE intentionally waited for several days before actually doing that.
have you read the BIBLE? read it, again, and again, and again, and again, until the day you stop breathing. only then can you gain understanding on GOD's character and behavior.
you;re asking about some manual of this "cosmic slot machine" right? well, guess what, you ALREADY have it, the BIBLE. GOD even sends the HELPER, HOLY SPIRIT to help you understand said manual..
