There are plenty of proofs out there, but you have to care enough to be honest with yourself. Paroh managed to laugh off some pretty solid proof with hair-splitting excuses. Nothing can force someone who refuses to believe, to believe. But, to a believer, many things can offer a boost and protection, or shock absorber.
Don’t fool yourself. Emuna needs constant boosting. On this forum itself you can see how, during a crises, people lose faith or get angry at the One in charge. There is no room to tease yourself for the sake of perhaps getting S’char.
