Depending on your personal emotional makeup "trusting" in someone you can't see or speak to in any plain fashion
can be difficult.
As far as trusting people goes, I don't, don't trust them any farther than I can throw an elephant. I trust people
to do what is in their own best interest (with some caution thrown in for acts of stupidity) and no more.
I've had plenty of "terrible things happen", but I don't know if that helps or hurts faith in people, I've seen
various reactions to times of distress. When I found out I had cancer it was more mild surprise than anything else.
I've seen others that go into a more or less permanent panic.
With God, He has never let me down. It's not that I always get what I ask for, often I don't, but I get what
is "best for me at the time".
When I was younger and dead tired of trying to find a wife, I gave up and put it in His hands and said "Find me a wife
or a monastery, I don't care which." A year later I was married (and still am).
I collect rare plants, and at times I have asked for seeds that are essentially unavailable,
and shortly, they will be available, not free, not without some hassle, but available.
At work, things go smoothly with no real effort on my part, at home, my family is healthy and happy (more or less),
and problems that arise tend to work themselves out in time.
Thank God for what you have, be patient, have a little faith, and things will work themselves out (in time).
