This is a stronghold buster to help one who is struggling with impure thoughts or lustful thoughts (e.g. pornography). It is a declaration of Satan's lie with regard to this area and a declaration of God's truth and a list of verses to daily meditate on which will help develop purity in one's thought-life. You should read through these verses once a day for 40 days. "For out of the heart come evil thoughts, murder, adultery, sexual immorality, theft, false testimony, slander." (Matthew 15:19)
