”Most men will proclaim every one his own goodness: But a faithful man who can find?“
Proverbs 20:6
Taking the idea being presented in this passage and trying to explain the nuances would be a lengthy endeavor. There is a maxim which encapsulates the idea quite well, “Talk is cheap.”
With that statement in mind, we will re-phrase the passage:
An abundance of people will accost you to talk about how amazing they are. But it is very hard to locate a person that is trustworthy.
If you want to be a rare find, be trustworthy.
