The languid success of logic and facts to dislodge believers from their mistaken beliefs, calls for a new course in the claim for morality's mantle; religion fails humanity on ethics.
There appears to be no amount of reason or facts that will extricate believers from their cognitive biases, or the nucleus of their intractable, mistaken, and teleological beliefs. Non-theists, in my humble, yet scholarly opinion, need to set aside the Pathos and Logos based arguments. Instead, nonbelievers must begin to advocate on the ethical grounds, that, revealed religion is an antagonist to humanity's progress and ultimately, its survival. It usurps our innate nature of goodness, and transgresses on our naturally earned ethics.
Further, consider, the believer must first successfully defend the idea of providence, which they cannot, and then, the veracity of such a notion, which has been an abysmal failure for the faithful. The devotees of Christ, fortified only with ancient apocryphal and worrisome scripture--putting it mildly, cannot attempt to mount a defense that religion offers us a moral mapping of the mind. In fact, instead, I would argue on the offensive--on the immorality of Christianity.
Chiefly, a person of Christian religious belief needs quite a bit of instilling indoctrination, in fact utter brainwashing, to convince one's self that they, for merely being born, are worthy of "Hell" because an alleged ancient ancestor ate of a forbidden fruit--the idea of "original sin." Christianity edifies, and thereby institutionalizes, the fallacious concept of salvation through willful subjugation and degradation of our native decency. (This is why, mistakenly, "Christ followers" feel they need a "Savior.")
