Words can have a negative effect on your mind. What is in your mind is in your heart. Some of Jesus' strongest words were directed at outwardly rightous people but corrupt in their thought's (Matthew 23:27). Behind everything we do is a thought whether for good or for evil. You may not even be aware at the time but we never act unless we thought about it Out of our hearts come evil thoughts (Matthew 15:19).
The way to safeguard your mind is to avoid anything that fills your mind with evil thoughts. Fill your mind with good things through prayer and reading the Bible.
Begin by committing your life ( this includes the mind) to Jesus so He can teach you more about Himself. That way Jesus will become the focus of your mind and heart everyday.
