Matthew 15:19

For out of the heart come evil thoughts, murder, adultery, fornications, theft, false witness, slander.

Now the deeds of the flesh are obvious: immorality, impurity, lewdness,

But Jesus, knowing their thoughts, said, "Why do you think evil in your hearts?

For from within, out of the heart of men, come evil thoughts, fornications, theft, murder, adultery,

Repent therefore of this wickedness of yours, and pray to the Lord that, if possible, the intent of your heart may be forgiven you.

As it is written: "There is none righteous, no, not one;

For I know that nothing good dwells within me, that is, in my flesh. I can will to do what is good, but I cannot do it.

For the mind that is set on the flesh is hostile to God; it does not submit to God's law, nor can it do so;

And you were dead in your trespasses and sins,

to speak evil of no one, to be peaceable and gentle, and to show true humility toward all men.

Let no one say when he is tempted, "I am being tempted by God"; for God cannot be tempted by evil, and he himself does not tempt anyone.
