Jeremiah 16:12

For it is from within, out of the hearts of men, that there come evil thoughts--unchastity, theft, murder, adultery,

but wicked people and impostors will go from bad to worse, deceiving others and deceived themselves.

Be careful, Brothers, that there is never found in any one of you a wicked and faithless heart, shown by his separating himself from the Living God.
