Philosophical arguments not only don't lead to a personal god, they tend to lead to a rather limited one defined by the particular proof. Thus the designer, the first mover, the thing that has always existed and so on. None of them is much like the god of Abraham, Isaac, and Jacob. Nor do most of them lead to a god that is necessarily still in existence. Could the first mover have expired in the effort? Why not. Same problem with the designer.
If there is a god, I want to believe that there is a god. If there is not a god, I want to believe that there is no god.
