Matt 15:19
For out of the heart come evil thoughts, murder, adultery, sexual immorality, theft, false witness, slander.
Rom 8:7
For the mind that is set on the flesh is hostile to God, for it does not submit to God's law; indeed, it cannot.
Jas 1:14-15
14 But each person is tempted when he is lured and enticed by his own desire. 15 Then desire when it has conceived gives birth to sin, and sin when it is fully grown brings forth death.
