Treasure of the Heart

A good man out of the good treasure of his heart brings forth good; and an evil man out of the evil treasure of his heart brings forth evil. For out of the abundance of the heart his mouth speaks. (Luke 6:45)

When a person is good, their heart overflows with the goodness and mercy they received from God, and they have love and understanding to offer others.

But those whose hearts are full of bitterness and wickedness live swearing and causing confusion. Thus, they end up blaspheming against God because they do not know the Truth that delivers and saves.
