It is not wrong to base belief on illogical reasoning. It is, however, risky to assume that others will give the same degree of verity to the conclusions reached.

TT makes some very interesting points, especially the suggestion that the burden of proof for the existence of god is one that is easier to agree with if the person has already had experience of something that could be described by them as evidence of god. If belief in god is a desirable aim for someone then I suggest it will be easier for that person to make a free (whether true belief can ever be the result of coersion is another topic!) declaration of belief. Faith is a personal decision. If faith/belief is there then god (in the various manifold manifestations) will exist for that individual.

I do not think that "relgious division " has much to do with god and much more to do with all too human ego and illusion. (Similar to TT).
