You are right, there are always more neighbours in need, and that has to be because we do not treat each other fairly. It is not right that twenty thousand children should die every day as a result of grinding poverty and preventable disease.
If you take care of one, but not the other is it hellfire for you? If you only have enough to support yourself, are you in trouble with your god for not giving it away anyway? Way too many variables.
If you live in fear of God and hellfire, you can struggle with all those questions. To be a part of the solution you have to try and do something.
I am quite certain "Hindus, Muslims, Christians Sikhs and everyone else" do not describe their gods as you describe yours. So either they have their gods and you have yours, or a bunch of you are wrong about the nature of your god, or no gods exist. Since you are discussing the nature of the god of your bible, and not any of the Hindu gods, I will refer to it as "your god"
I can't talk for all religions, but I assume most religions believe in a God that created the universe and life, all that is seen and unseen. We are all a part of God's wonderful creation, we each have a duty to care for God's creation, that has to mean caring for each other, despite our differences. We are all just temporary custodians of whatever we might own, the sustainability of mankind depends on what we can pass on to our children and grandchildren's generations.
I believe that the fear of God helps us focus our minds on the needs of others.
