One thing that I learn the heart can be good but evil too.
If your heart is a fleshy heart than it can be good heart.
While if it has been harden, to a stone heart it is evil.
This was why Psalmist King David ask for a new Heart.
Because His heart has harden into an stone heart already.
So if someone like Him who was super blessed by Jesus.
Then a normal person like I , my hearts may have been harden.
Without even I even realizing that my heart has been harden.
So I need to do a good/ evil checkup of my heart here.
