So many people don't know what faith is, they want proof.
Can faith-based claims be rationally justified? No.
Faith is the assertion (or hope) that one's beliefs are true. It is epistemologically barren. Some attempt to argue that faith is "belief without evidence". Such people sometimes attempt to equivocate "faith" in their preferred God with "faith" that the sun will rise tomorrow or "faith" that their car brakes will work. When analyzed it becomes apparent that "faith" in one's car brakes and "faith" in one's preferred God are so fundamentally different and based on such different approaches that equivocating the two is as fallacious as it is disingenuous.
I'd be more than willing to discuss the merits of faith-based claims if you wish.
All I am concerned about is that it is worth believing, and does it make you a better person.
I find this is sentiment common among theists. That belief in something, even if it is false, provides the benefits of comfort, happiness, and moral superiority. Such a claim is indefensible and as such it is baseless as it is unjustified. But that does not stop preachers and pastors from using such a specious argument when "preaching to the choir" or when attempting to convert ignorant or credulous listeners.
I would propose that seeking truth is of the greatest importance as it gives one a greater ability to make decisions and actions that are most effective and that reflect reality to a greater degree. If happiness and comfort are what you seek then I strongly advise seeking knowledge to obtain that state of mind rather than being credulous to the unverifiable and indefensible specious claims of others.
There is no proof, looking for it is a waste of time...
Conceding that a particular worldview cannot be validated with evidence makes it indistinguishable from truth, falsehood, fraud, imagination, or mistake. Such beliefs have no necessary relevance to reality and as such are of no concern except perhaps as entertainment.
let your faith and the good teachings guide you, and disregard the minutae....
I couldn't disagree more. Such platitudes may go unquestioned when "preaching to the choir" but not to others who will evaluate the merits of such a claim.
Can you defend the claim that:
1) following "good teachings and faith" is superior to other methods? E.G., reasoned and rational conclusions developed from tried and tested experimentation?
2) In what scenarios is relying on faith superior to relying on conclusions developed by verifiable evidence and reason?
