I don't usually pray a lot but in the past few days, I have been asking God for help to get through the day and the willpower not to break down and cry. And I feel guilty about asking for these things.
Let me explain what I mean. I believe prayer is a person's chance to talk to God. When you start asking for things, it's selfish and you shouldn't be asking things from God. I don't even think asking for guidance or willpower should be asked for. If you really ask for something, it should be unselfish (i.e. not for you) - a cure for AIDS, an end to poverty, etc. Not for good examination results.
At times I really wish I could have reply for my prayers.
