Prayers

Dear Friend,
Here is my opinion,
I think Prayers provide a sense of spiritual peace and comfort. Prayers offer relief when we can't do anything about a problem. But Prayers never produce anything physical.
From my personal experience and my many failures and few successes, I think it is just simple math; 1+1=2.
If you do nothing, nothing will happen. If you do something, something will happen as a result. If you add 1 to 1, you get 2. If you add prayers to 1, you get 1+prayers which is still a 1 in the physical world and never a 2.
A house will never miraculously build itself by praying. It must be constructed by people and materials with no mistakes so it wouldn't collapse. 
If you do not study Physics, you will fail a Physics test. If you pray all the time, Physics will never come to your brain.
We depend on begging God when it is out of our hands, when it is 50/50, or when we are unable to do it ourselves. If people work hard, and things go their way, they say our prayers worked. But, when things do not go their way, they say "God works in mysterious ways." only to make themselves feel better and justify the lack of hard work, working the wrong way, or the bad luck in some cases. This is why helpless societies rely more on praying than nations with freedom and equal fair opportunities.
You will notice that societies depended strongly on prayers rather than honest hard work do not advance and have higher crime rates like Egypt, Pakistan, Afghanistan, Mexico, Colombia, Guatemala, and even the United States. Atheist Nations which do not pray and just work hard are more advanced and have a lower crime rate like Sweeden, Norway, and Denmark for example. Peace
