I remember using a coke bottle or a hairbrush as a microphone and interviewing my friends about school dinners and grumpy teachers.

They must have been as mad as me, because they always spoke into the imaginary microphone and emptied their hearts.

Well, I don't know whether I'm just naturally curious, or maybe downright nosey - but I ended up being called a snoop!

It wasn't just my unsuspecting friends I interrogated, I also had lots of questions for the teachers too.

And my favourite place for firing the questions was in religion class.

Being brought up in Northern Ireland, it really bothered me how much religion was blamed for all the suffering and division.

Indeed, it's only when tragedies occur, like yesterday's terrible train crash, that we transcend the religious barriers and unite in our heartfelt prayers for the victims and their families.

But the burning question for me in my teenage years was this:

"Why are there so many different religions in the world - and wouldn't it be great have just one religion for everyone?"

It was this question that started me out on a spiritual quest for truth, which finally led me to Bahá'u'lláh, Founder of the Bahá'í Faith.

Bahá'u'lláh proclaimed that there is only one true Faith - the Faith of God, and that all the religions are, in reality, different stages of that one Faith.

The world's different religions, He taught, have "proceeded from the same one Source and are the rays of one Light."

"There can be no doubt whatever," wrote Bahá'u'lláh, "that the peoples of the world, of whatever race or religion, derive their inspiration from one heavenly source and are the subjects of one God."

So if anyone were to ask me the question: How many different Faiths are there in the UK today?

I'd need to do a quick count - Judaism, the Zoroastrian Faith, Christianity, Islam, Buddhism, Sikhism, Hinduism and the Bahá'ís. And if I've counted right, that adds up to … one, just one Faith in the Nation.
