I think sometimes Heavenly Father allows us to be tried. I’ve experienced a couple of times when decisions have been confirmed by the Holy Ghost and then I encountered either difficulties or huge trials.

At least once I have had the thought, “Why did you do this to me?!” And at least once I’ve thought, “Why did you even create me?!” So, I understand how someone else could think that.

But, I am learning that our Heavenly Father is REALLY our Father (in the best sense of the word.) He wants us to be happy even in the midst of trials, to put our trust in Him and allow ourselves to be calm and not controlling, to savor peace and not sow conflict between ourselves and Him. I am learning that becoming a disciple means developing self-discipline–not just to be obedient to promptings but to be patient and see those experiences through to whatever resolution Heavenly Father intends.

But apparently unlike you, I’ve also had moments when I personally thought the light was red, but God told me it was green, so I went. A semi truck hit me. Turns out the light was red after all. If that has never happened to you, lucky you. But it only takes one such experience to know that God is not trustworthy after all. I refused to believe it at first, and was “blessed” with several more semi crashes.

You can’t know someone is trustworthy after one experience with them, probably not even “several moments” would be enough in getting to know most people. Anyone who has dated knows that a person might be attractive and pleasant on a first date but sheer horror once they think they have you hooked. A person might be a fine, upstanding citizen in public, but a rogue in private life. But you know that God is perfect all the time based on several moments of interaction with him.

How can it not be blind faith to put complete trust in a God who has proven himself to some, disproven himself to others, and proven to be mysterious to almost everyone. To say that God has proven himself is to willfully turn a blind eye to contrary evidence in your own life (those moments of actively doubting or at least not-knowing or not-being-sure interspersed amongst the moments of knowing) and the lives of others (reports from people who pray sincerely for decades yet never receive discernible answers, or who are sincerely led astray, for example). I’m not saying you should look at that evidence, of course. If you prefer not to, then don’t. But that contrary evidence is there, you cherry-pick around it, and you say your faith is not blind.

“I think I can handle things myself when it has been repeatedly shown to me that I cannot.”

That is true of a lot of people. Also, a lot of people think they cannot handle things themselves when it has been repeatedly shown to them that they can. How does teaching “lean not unto thine own understanding, because God thinks you are, to put it bluntly, so incredibly STUPID” affect those individuals?

Sadly, I still forget.
