Deep down inside, every single person has some traits in them that, at its best, is annoying; and at its worst, detestable, to other people. (There is no shame in acknowledging that I myself have these faults)
I believe that whatever you choose to think of a person will be what that person will be to you. If you choose to see that a businessman who made one accidental mistake in his career is a crook because of that one mistake, he will continue to be a crook to you despite his subsequent behavior of integrity and justice.
It's strange how it works, but I do believe this is how we get by with people we THINK we cannot tolerate in life.
Likewise, it is also of utmost importance to think of people on pedestals as mere humans - ever ready to soar among the eagles yet always at risk of falling to temptation as their lives go on.
Note to self: For every one person you put your trust in, you must also learn to put more of your trust in the One who will never fail. The One who remains unchanged yesterday, today and tomorrow, and way into the forever of the future is the one constant.
"Trust in the Lord with all your heart, and lean not on your own understanding;
In all your ways acknowledge Him and He will make your paths straight."
