How do you define the terms "believer" and "unbeliever"?

Believer: one who believes in the God of Abraham, whether that person is a Jew, Christian, Muslim or Baha'i

Non-Believer: one who does not believe in the God of Abraham

P.S. I like scientists, they use their brains for the betterment of mankind. I've even met a Baha'i scientist and she was cool!

everyone believes in something . science in facts and Evolution. problem with the term unbeliever is that they do believe in the same things just in a different package but the package the beliefs are presented in do not matter so much as the contents which are similiar so there can be no unbelievers in religion as that is what is required. A real unbeliever is someone who does not believe in the law thinks it all right to torture,murder, and control the resources of others or enslave other people ,despoil The Earth, rape, not believe in the humanity of humanity. this is an unbeliever who in doing so by extent does not believe in their own humanity. not out of religious belief but for reasons at times humans in much of the world have been guilty of which means they are nonbelievers who lay claim to a belief in the law or a supernatural entity but do not believe in either at least not truly at least not yet . neither do they believe in morality because if they did they would have done none of these things.

As far as I've seen it is what christians use. They use believer for christians, unbeliever for everyone else.

I think it's a bit of arrogance myself-they should state their particular religion, as they could be believers in Zeus, Allah, or Odin.

The other part is (I think) that they get made fun of too often about not being able to spell atheist.

A believer believes something. An unbeliever is a scientist.

A believer is someone that has accepted Jesus into their heart and believes that what Jesus did on the cross is the way to salvation.

A unbeliever is one that may now that Jesus existed but does not accept what Jesus did on the cross as the way to heaven and eternal life.

Even Satan and the demons believe in God and they cursed to eternal damnation.

To Christians it simply means one who believes on the Lord Jesus Christ..and one who does not.

A believer follows the example set by Jesus Christ.

A non-believer rejects the example set by Jesus Christ.

I don't.

The terms are far too vague and general.

A believer in what?

A believer of what?

One should be more precise.

Believer is someone who believes

Unbeliever is someone who doesn't beleive.

I unbelieved my faith in God.
