I think that Star Trek can benefit from portraying religion in a positive and curious light like in Deep Space Nine.
However, I realize that that might be hard to do, since most of the Federation has embraced secular humanism, and the only portrayal that I liked, from DS9, came from the top ranked Star Fleet officer being ordained by other religion based on another planet. Thought, you can from the shows see that sometimes it seems like they make whatever religion a humanoid believes in them is real to them... like Sto-Vo-Kor... and there are probably other examples... I know that religion can be a touchy subject... but Trek hasn't completely shied away from the controversial.
