I often hear people thank God about how their prayer being answered such as in competition. But what I'm thinking is, the winner is not absolutely the only one that prayed. I believe everybody in the competition pray and hope to win too. So, in this condition, only one person's prayer will be answered.
So, how does God decide which person's prayer to answer? Is it based on how hard s/he prayed, or how much s/he deserved it? or is it according to His will only?
If none of them pray, will the result be the same?
