The world is religious in the majority. The impact of religions in our society is immense. Religions are the cause of many evils. The biggest evil currently being Islamic terrorism. Others: Church missionaries and monopoly, superstitious belief systems, etc. The root of these evils is sometimes in religious texts itself, but I would majorly attribute it to charismatic and passionate religious leaders who heavily influence masses through their ideologies and propaganda. To add to that, they are heavily funded by believers. Money and strong belief system make it very difficult to fight these evils.

We are in the 21st Century. Technology, science has progressed leaps and bounds. An educated mind should naturally question: “Why is theism still relevant? It’s the source of so many evils. Shouldn’t we fight against theism to fight these evils?” The answer to this is, in my opinion, a resounding yes. Religious belief systems today are heavily corrupted. Take Churches, Mosques, Temples for example. They are massively funded by organizations. To add to that, they accumulate huge wealth due to mass donations. I have mentioned earlier, how charismatic, corrupted religious leaders are the source of religious evils. It’s difficult to fight them. The reasons being centuries old stiff belief systems, blind mass following, and sometimes the core ideologies of the religion itself are flawed.

Well, I have so far ranted against evils of religions. But the question is, “Why do I still believe in God?”

Simple answer: Srimad Bhagavad Gita.

Long answer:
Our Universe is so vast, immense and we know so little about it. Even the things we know turned out to be wrong after the evolution of quantum physics. The observable Universe is at-least 46billion light years wide in diameter. But when we talk about God, we associate him with petty human natures like love, desire, hatred, punishing. In Bhagavad Gita, Krishna declared himself as the ultimate God. He creates everything, he destroys everything. Universes are created and destroyed just by his breath. He doesn’t control human fate. Human fate is governed by their own karma. He is above all human virtues.
It is not possible for the human brain to comprehend true nature of God. However, it is possible for us to love and devote ourselves to God and perform our karma. In Bhagavad Gita itself, Krishna has said that he only looks for the true feelings of the devotee and not what he is donating or spending on rituals. He can be made happy just by leaves, flowers, or even just water.
Of course, I can be an atheist and perform my karma. But for me, being in the state where I can look for Krishna is more satisfying. Besides, there have been significant scientific findings in the fields of reincarnation and near-death experience which points towards non-materialistic nature of our Universe. Reincarnation stories: Beyond conventional science. In a non-materialistic model, being a Krishna devotee is cool as Bhagavad Gita itself preaches about non-materialism and temporary nature of this materialistic world.
In any case, materialistic or non-materialistic, the biggest reason for me being a theist is due to the fact that Bhagavad Gita changed my life. It significantly changed the way I think. I helped me a lot. And the things Krishna said was so meaningful, relatable and enlightening on so many levels. Even if it’s all fiction and written by an unknown poet, that poet for me is no less than a Guru. And in Indian traditions, Guru occupies a position even higher than the God himself.
