Trust is like glass. Once broken, it will never be the same again.
Faith is the way we perceive and trust a person, or something. Sometimes people can easily sense your realiability, and they easily trust you.
But most beliefs are built over a long period of time, they need to go through interaction with you, even through doubts and misunderstandings, in order to understand who you are, to love and put the trust in you.
It’s hard to build trust, but just once you act against what they believe, their beliefs will shatter like pieces of glass and can not be healed as before.
Because they feel betrayed. Even if they are not blaming you, the frustration is still smoldering inside them. They will never trust you again
