This is an era of science in which humans are everything. All the stuff we heard about god is only in the books and there is no proof of god (if there is, then I don't know about it). At a time like this how could we really convince ourself and others that there is god? What is the need of worshipping since it's nowhere written to worship god?
The question started with the statement
it is an era of science in which a human is everything . All the stuff we heard about god is only in the books and there is no proof of god
and ended with the statement
What is the need of worshipping since its nowhere written to worship the god?
Can we prove to the satisfaction of a questioner, the Newton's 3rd Law - For every action, there will be an equal and opposite reaction - only through reading/explaining?
Not possible, because it can only be experienced.
In my view, no body can provide any authority from any scripture, for conclusively proving the existence of GOD, because the concept of GOD is an ABSTRACT thing, which can only be experienced, but cannot be proved.
Personal experiences/Holy books/Logical arguments are useless to convince anyone that GOD exists.
So let us limit our focus on the issues that are known to every person.
Everybody might have heard the undermentioned words. These are illustrative but not exhaustive.
Every rational human being with reasonable exposure to the society around him/her might have experienced the above mentioned feelings at one stage or other of his/her life.
My question is, is it possible to explain:
For any rational human being experiencing one or combination of two or more feelings mentioned above, in words or make understand another person, who have no firsthand experience of that feelings, how the feeling look like, effects his/her personality?
Why a particular person driven by compassion towards human beings, will leave behind his/her riches/fame/position (like Buddha), works for upliftment of society, living on bare necessities?
What is the cruelty that provoked Adolf Hitler to butcher thousands of Jews?
It is not possible because it is feeling and an ABSTRACT thing. And, it is intangible and cannot be explained in words.
The feeling is a force/energy that can either positive or negative. There are many visible and invisible forces working in this world.
The known and unknown negative feelings/forces put together will be known as GOD. And, it is also an ABSTRACT thing.
It can neither be explained in words nor evidenced by personal experiences of other people.
It can only be experienced.
Neither the believers nor non-believers of GOD can know the TRUTH. Only a sceptic mind with the intent of knowing the TRUTH will realise the TRUTH.
Let us consider one more example:
If somebody wants you to describe the taste of sweet in words, can you do it?
Even if you try to explain the taste of sweet for 1,000 days, the questioner will not understand. Just put a lump of sugar in his mouth, then he will understand, as taste can only be experienced, as it is intangible.
Similarly, God is an ABSTRACT thing. Nobody can describe it. You can only experience it.
