I long ago learned to be ambivalent.
Religions have given us ridiculous concepts about God and we have foolishly believed them (or been afraid to contradict).
Even if we faithfully believe the words of Jesus, none of what He said was written down at the time and we all know how things are 'embroidered' as they are passed down.
It's utterly foolish to blame God for the things evil and greedy men do.
If we truly and genuinely expect a loving God to stop wars, pain, suffering, why don't WE act in His place and do it?
I have seen miracles. In just one case, a child with 2 brain tumours and in her last days at Starship Hospital here, was healed by a man about whom I was writing a book. He had hundreds of testimonials of healing.
But even then, I was asking 'why this child?' Did I really believe God had decided to cure this one little girl and ignore all the others in the Oncology ward?
It's because we cannot answer such questions we feel helpless and bitterly blame a God we don't really believe in.
But if God (or the concept of God) has brought comfort and healing to people, then that can only be a good thing.
If God has generated a sense of dedication and purpose (as with Mother Teresa and many others), then that is His worth and His work, in this world.
