If for every well-intended prayer uttered in hopes of making the world a better place, there was instead a good deed accomplished, the world might look as though those prayers had been answered.
Miracles are commonplace in religious scripture. Our ancient ancestors are said to have felt Jesus' wounds, verified Muhammad's ascent to heaven, and even interacted with their respective deities directly. Today, believers have no such luxury. They are forced to rely on blind faith that these things occurred, that people were at one time able to overcome or render inert natural laws.
While it may be impossible to 'disprove' the existence of some 'Higher Power' or abstract Creator, it is entirely possible — through analysis and research — to find discrepancies within the ancient, organized religious traditions that support the idea of a specific God.
Prayer doesn’t work. Perhaps it makes the believer feel better (in the same way that meditation or deep thought would), but prayer doesn’t actually affect the external world. Not only is it ineffective, but it is also a very narcissistic practice… why would a 'God' change its 'Divine Plan' to accommodate any person’s wishes?
Not only do I believe that it is possible to maintain moral standards without the crutch of religion but I would argue that it is the only way to achieve true goodness.
It is my sincere opinion that our precious time on earth should not be spent attempting to justify unbelievable acts of cruelty, death, and disease as a part of 'God’s Plan' or the greater good — and clinging to ancient texts that preach ill-concealed bigotry and sexism. Instead, we should find ways to make this life happy and satisfying, without regard to the unknowable nature of an afterlife.
