When Adam and Eve were made they were given free will to decide what to do and how to do it and take the consequences. Hence their ejection from paradise went they ate the apple they were told not to eat.
I have never believed that God interfered directly in peoples lives, all you can do is ask for his grace and wisdom to guide you in your decisions.
So many things people ask God to do act to disadvantage to other people. Whenever people pray to get a job, get to the right university and so on, it mean that if granted, someone else fails. If you believe in a loving God, he soon becomes a transactional God; if you help me pass this exam, I will give money to charity, never drink again or whatever.
Once God has given us free will, he has stepped back from interfering in our lives. It is just when things go people's way they thank god, and if it doesn't they abuse him. I think the best sign of his ultimate wisdom was his decision to step back and not get involved.
