I am not an intellectual or expert about religion. But my small mind can tell one thing confidently, that concept of Religion came to existence far far after life came to earth. Means life is first and then religion or you can say religions are for humans and not other way round.
We can say religion came to existence for
1) To make human’s life comfortable by giving them path to follow for living
2) Make human social animal
3) During socialization fix some rules, regulation, rights for living
4) Give some logical explanation to the things that are not understandable to general people etc. and may be some other reasons.
But one thing, none of the religions will ask you to waste your own life or kill other’s – excluding some exceptional cases like self defense , for saving somebody, to stop injustice etc. If so,
1) You must have misunderstood the thoughts and you need to revisit and learn it again.
or
2) Somebody must be misleading you and you need to stop following or listening him, also tell others to stop.
or
3) Thoughts might be correct, at times when it was written or told and it was not changed as per time, so you need to rewrite them for the betterment of humanity.
or
4) You are following wrong path and needs to change it before it’s too late and help humanity to grow
or
5) Someone with very good brain is using you for his benefits, so use your brain wisely before it’s too late
Because religion will exist only if humans are saved.
By taking lives, at the end not a single religion will exist.Lives are the base for any religion.So be clever human before it’s too late and stop killing self and others in the name of religion, doesn’t matter what religion you are following.
