Anyone with sincere religious beliefs cannot say that all religions are true. That is so illogical it is pathetic. All religion cannot be true because some of them are so diametrically opposed to each other.
I don't know what I would have done without believing in God. His support gives me power and energy to continue to be optimistic to smile not to be depressed. Sometimes if things are not going so well I don't cry. I say maybe it's meant to be.
