gracie said:why wouldn't it be? is faith not a justifiable answer to others' questions?
e.g. "i take it on faith that this book is from God"
I guess when people say it's all about faith, so they just try to use this answer to avoid answering 'some' questions which their religion can't afford it.
For me personaly, Islam fill up my whole mind and soul and it also have answered all my questions. It's not only about faith because my faith came after accepting islam by my mind in the first place.
