• Matthew 15:18-19
    But those things which proceed out of the mouth come from the heart, and they defile a man. For out of the heart proceed evil thoughts, murders, adulteries, fornications, thefts, false witness, blasphemies.
     
  • Mark 7:21-23
    For from within, out of the heart of men, proceed evil thoughts, adulteries, fornications, murders, thefts, covetousness, wickedness, deceit, lewdness, an evil eye, blasphemy, pride, foolishness. All these evil things come from within and defile a man."
     
  • Proverbs 4:23
    Keep your heart with all diligence,
    For out of it spring the issues of life.

     
  • Matthew 12:34
    Brood of vipers! How can you, being evil, speak good things? For out of the abundance of the heart the mouth speaks.
     
  • Romans 7:15-23
    For what I am doing, I do not understand. For what I will to do, that I do not practice; but what I hate, that I do. If, then, I do what I will not to do, I agree with the law that it is good. But now, it is no longer I who do it, but sin that dwells in me. For I know that in me (that is, in my flesh) nothing good dwells; for to will is present with me, but how to perform what is good I do not find. For the good that I will to do, I do not do; but the evil I will not to do, that I practice. Now if I do what I will not to do, it is no longer I who do it, but sin that dwells in me. I find then a law, that evil is present with me, the one who wills to do good. For I delight in the law of God according to the inward man. But I see another law in my members, warring against the law of my mind, and bringing me into captivity to the law of sin which is in my members.
     
  • Romans 8:7
    Because the carnal mind is enmity against God; for it is not subject to the law of God, nor indeed can be.
     
  • Matthew 5:27-28
    "You have heard that it was said to those of old, 'You shall not commit adultery.' But I say to you that whoever looks at a woman to lust for her has already committed adultery with her in his heart.
