Filling in the stages of argument by which this is achieved - anyone like to try?
I know that conceding there is a necessary being in the first place is based on some pretty shaky reasoning (for me, and no doubt for quite a few others). But if the possibility could be conceded, how does one progress through all the possibilities to arrive at such a specific conclusion from all the theistic options available? I will cite just one which is the worst of all scenarios - the possibility that we are just here for the amusement of some megalomaniac tyrant who created us, without any hint of love at all. There obviously would have to be some possibility of love and beauty in the original mixture, otherwise the whole show would have long extinguished itself (it has of course been touch and go sometimes, as it seems to be right now).
Yet all the main world religions seem to have concluded that the supreme being is ultimately good, though with some remarkably different takes on what exactly 'good' is supposed to be. Far easier to sum up these matters of theodicy by dispensing with the idea of a necessary being all together. The vast panorama of evolution, filled with horror and pain, and on several occasions, near mass extinctions, are better explained by neo-Darwinian theses, than theological ideas, for me at least.
