Waheguru ji ka Khalsa, Waheguru ji ki Fateh,
I am replying late so many might have pointed out same things as mine. Sorry for repeating.
1 - According to Sikhism, and in fact every faith, one achieves salvation by 'obeying God' or submitting to him/accepting his will. Forgive me for saying, but this makes God sound like some egomaniacal dictator in that he only rewards people who suck up to him. Why does God require us to do this if he is all-loving?
Everyone is free to interpret God like they want to. But no one connects to how Guru describes God.
2 - The main objective of a Sikh's life is to become 'one' with God. And yet paradoxically, Sikhism states that we are already 'one' with God. If we've already reached the destination, then what is the point of leading a religious life? What are we supposed to strive towards?
There is a difference between being in an organization or being devoted to an org!
3 - I fail to understand the idea that God is 'inside' of us. What does that even mean? Inside of what exactly? He can't be inside our bodies as he is not physical and scientists have yet to detect anything that suggests a physical presence of him within us. Is he within our souls (But our souls aren't physical either, so how is he inside of those)? If so, please elaborate.
Where are your thoughts? Where is your mind? Science doesn't know if it exists or if it is physical?
4 - If all paths lead to God, then why was it necessary to create Sikhism, if other religions already offer a path to salvation? In other words, if being a Muslim, who cuts his hair, can lead to liberation, then why bother going to the effort of keeping kes? If the response to this is Sikhism is the only path that leads to God, then I am definitely leaving the faith, as acceptance of others is what inclined me towards it.
All religions are different explanations and paths for your journey to God, you stick with what you get first or understand the best! Sikhi for Guru Nanak was all about spreading the love!
5 - Several miracles are supposed to have taken place in Sikhi and indeed all religions. Why is it that 'miracles' have only taken place centuries ago when there were no cameras and why are there so many contradictions with regards to miracles in Sikhi? - we have on the one hand, Guru Hargobind Sahib, whos heavily reprimanded Baba Atal Rai for performing the miracle of bringing his playmate back to life, and then on the other hand we have Guru Gobind Singh resurrecting the Panj Piare after beheading them, and Baba Deep Singh fighting with his head in his hand.
A miracle is an inexplicable event which amazes most people, but they leave it as it is, not trying to understand what happened. A Sikh gets the Truth out of the miracle.
6 - In Sikhi, we keep our Kes because we are supposedly forbidden to change the God given form in any way. Therefore, according to Sikhism, people who are born with severe physical defects are prohibited from recieving surgery to alter this as it would be changing their god-given form. Is this not hypocrisy?
It is all up to the individual. You have been given guidelines. Your faith will take you places.
7 - In Sikhism, we believe everything that happens is God's will and we should accept what happens unconditionally, as it is part of God's will. By that logic, because Operation Bluestar happened, should we not accept it and not complain about it, because everything that happens is God's will is it not? Even Guru Arjan Dev Ji said his killing was God's will. So why did Guru Hargobind raise his sword against the Mughals if they were simply enacting God's will?
Indian constitution guarantees justice as effect of any cause e.g. crime. Bluestar was a crime and there has been no justice. We are protesting that the system is broken. Guru Hargobind Sahib raised his swords because Mughals were going from bad to worse. And we can't even understand the importance of Shaheedi of Guru Arjan. It has much more complex and deep implications!
8 - Does God grant mukhta to good people who do not believe in him? Would God condemn me to another 84 million rounds of reincarnation for not believing in him in the face of an incredible lack of evidence?
I haven't met a single person who doesn't believe in God. Non believer would be a guy going mad saying the world is unreal, he is trapped in the Matrix and jump from a roof to try waking up!
