Firm reliance on the integrity, ability, or character of a person or thing.
I've been reading the book of Acts. And in Acts there's an amazing, jaw-dropping, UNREAL - almost unbelievable conversion. Saul becomes Paul! Saul was a murder. He was an enemy. He was passionate about his cause - though it was wrong. One day, he's blinded and when he regains his sight, he gains his SIGHT! I mean, there is a complete 180! He becomes one of those he persecuted. And for a bit, followers of Jesus weren't sure that he could be trusted. Until of course, he shared his passion about the gospel.
CAN YOU REALLY TRUST PEOPLE!?
There is a reason why the scriptures are flooded with words like (and this is just from the psalms, but seriously it's all over):
Do not put your trust in princes, in mortal men, who cannot save.
It is better to take refuge in the LORD than to trust in man.
We have the tendancy to put our hearts out there - I mean, not even romantically speaking - you put your heart out there only to find out that this person was not what you thought. And your world is messed up for a bit, because you can't find which way is up. When all along we're told - it's better to trust in God, than man.
