Stars represent actual masses of burning hydrogen.
But do any religion or any religious scripture can explain what a star is, or how they work.
And as to your own answer - "burning hydrogen" that's not strictly true.
There are no "burning" involved in a star.
And the actual masses are hydrogen atoms.
Burning mean combustion which involved fuel and oxygen or oxidant agent. And when mixed together, chemical reaction occurred between fuel and oxygen.
In chemical reaction of combustion (or burning as you would call it), you have a fuel, to give you an example, methane.
Methane, like most oil and gas, are hydrocarbon-based compound, meaning it a number of 4 hydrogen atoms bonded together with 1 carbon atom, hence looking like compound of hydrocarbon (methane) may look something like this:
CH4
When combustion of methane occurred it will require oxygen, so you will get this:
CH4 + 2O2 ===> 2 H2O + CO2 + heat (or energy)
Above, methane and air combust, and you will get chemical action that produce heat energy, water vapour (H
2O) and carbon dioxide (CO
2).
It start with 4 hydrogen atom, 1 carbon and 2 oxygen, and there are same number of atoms AFTER COMBUSTION.
What occurred in the star is a very different process, and don't require combustion or chemical reaction. And you need to have some basic understanding of nuclear physics, more specifically nuclear fusion, to understand the concept of "Stellar Nucleosynthesis".
Basically, Stellar Nucleosynthesis, used the same concept as nuclear fusion, so in the nutshell, the star is turning a number of hydrogen atoms into a single helium.
Where chemical reaction of any type (including combustion) occur, the nature of atoms and total numbers of atoms remain unchanged. But in a star's nucleosynthesis, you are changing lighter elements into a newer heavier element.
If you remember what chemistry teacher or textbook has taught you about the Periodic Table, hydrogen (H) has 1 electron, 1 proton and no neuton, while helium has 2 electrons, 2 protons and 2 neutrons.
To make a single helium atom, which include 2 neutrons, you would require a total of 6 hydrogen atoms. This form of nucleosynthesis or nuclear fusion, is called "proton-proton chain reaction".
It is too hard to explain in detail, about this so I will show you a graphic of turning 6 hydrogen protons to make 2 protons and 2 neutrons with helium nucleus:
The nuclear fusion of hydrogen causes high temperature, high energy and illumination. High heat application is what required to fuse lighter elements together, to form new helium nuclei.
Do you understand what I am saying here on how star heavier elements from lighter elements?
The Sun has no fire, because there are no combustion going on, and there are no carbon and no oxygen involved. When you look closely at the Sun, you think it is spitting out fire, but that is not what the star is doing.
What you are really seeing is plasma of hydrogen gas, being superheated, that the gas is being "incandescent", which provide light and heat.
Once the sun, run out of hydrogen into helium, if the sun core will collapse enough, to increase the temperature so that hot enough to fuse helium protons into heavier elements, like carbon, nitrogen or oxygen. If this happen, our yellow dwarf star will grown in size, turning into red giant star.
I would suggest that you read up star formation, stellar nucleosynthesis, nuclear fusion, to understand what I am talking about, and how the Sun don't "burn" hydrogen, or so you have claimed.
Institutions of higher learning are good at it too.
