Hi Naomi.
I know what you are saying and it's really tough reconciling all the possible reasons for not believing with those in favour of believing.
Dead bodies, do, in fact bleed and it is well documented that blood, is part of the fluid that collects post mortem and would have been a good clue that a crucified person was, in fact dead.
Jesus was not merely crucified. He had been flogged to the bone for a heck of a long time prior to the actual crucifixion during the 'procession' leading to his place of execution. He was already practically dead when the first nail was driven in.
My take on it is that I read the information available, spoke to many, many people from many faiths, and Christianity fitted the need that I had. Over the last few years, my Christian agnosticism has dwindled and I do, actually, feel that having faith has been the best thing I have done.
That said, you won't find me outside Woolies on Saturday mornings, tub thumping!
The tenets of faith - humanity, perseverance, humilty etc. are lessons that we can all benefit from, regardless of our beliefs and are worth sharing.
Christians (and indeed adherents of many faiths) have done a lot of wrong and followed many blind alleys. The way that some Christians present their faith can be arrogant, insensitive and parochial and that makes me shudder! But then, so do adherents of other faiths when they espouse their own beliefs.
My hope is that we, as humans, can transcend this and come together in our humanity and really come together as we face the challenges that the future inevitably holds for us.
You don't need to be a Christian to do that - nor do you have to be gullible!
