Personally, it's simple for me.

In the age when you can throw any claims, even the conflicting ones and still find reliable cold data and statistics to back it up, religion stands out as a bright dot that glows with a strikingly undying and constant strive for morality. (at least when you're able to spot an essence of it and ignore more of those nitty gritty trivialities the humans created) If some infamously under complains teachings go mostly unchanged for a couple of millennia is not a sign of otherworldly confidence, I don't think I know what is. It's even better when they sing of the virtues you personally endorse in sentimentalities. Warm and forgiving values that often dismissed as illogical by mainstream societies' standard, yet a gentle harmony from a perfectly tuned strings instrument in your mind. That would be a beautiful bonus.

Confidence can be good. When life tosses you around, everybody is saying different things all at once and intrinsic qualities of the much needed love is abandoned, those unmoved pillars of principles standing out, giving a sigh of relief at the familiar sights. Much like how those confident individuals are able to take a couple of deep breaths and stand up in the time of crisis no matter where they may be, looking straight into the depth of dark catastrophe - when all those frantic rats in their lines had fold over and reduced to silent, anxious side glances and pointing fingers. Ah. Those heroes, both sung and unsung. Don't we all admire heroes?
