Can you differentiate between a christian and a believer?

I think that most people who define themselves as "believer [but not 'Christian']" are people who have been brought up in a more or less Christian tradition or environment and have rejected the institution of the Church even though they believe in God and Jesus and the moral tenets of Christianity. They generally hold that the institution of 'the Church' (often the Roman Catholic church mainly but other churches as well) has moved away from the central Christian message (as taught by Jesus) and has become too secular and worldly, concentrates on increasing its own wealth at the expense of its members, exploits its members' emotions and fears and is generally corrupt. They define themselves as 'believers' in order to emphasise that they do not belong to any particular sect of Christianity and are not members of any particular Church as someone who calls him- or herself a 'Christian' generally does.

I am not religious, though I am spiritual. I, and many others, don't need to belong to any organized religion to "believe" in the Prime Source of Creation (God) and have a personal relationship with Him.

they might just mean they're not a "practicing" christian.

I do not belong to any religion. The best is to be kind to the others and do nothing wrong that may hurt other people. I see no reason to be part of a religion to say one thing and do the opposite. Look how many so called "good Christian" are racists or ready to spit hate.

One of the easiest ways to think about this is that a believer believes in Jesus where a Christian follows his commands. A believer will go to church on many of the holidays but a Christian will be active in a church and not just on holidays. We will always see a crowd in church at Christmas but not all the days that follow it.

Why are you so obsessed with religion?

i think that is Gnostic

i think the only time i would notice is when they say one thing but do the opposite

A believer believes what Christianity is all about and is not just an adherent.

No I have no idea for this theory if you have a some idea give me comment
