Matthew 15:10 (TPT) Then Jesus turned to the crowd and said, “Come, listen and open your heart to understand. 11 What truly contaminates a person is not what he puts into his mouth but what comes out of his mouth. That’s what makes people defiled.”

One of the things you must understand about thoughts is that, it can influence our emotions and behaviors, so if you want to see changes in your life, change or filter your thoughts, your life also will change. Choose to focus on the right thing, when someone say something negative to you, respond with God's word.

I heard Dr. Caroline Leaf says that "toxic thoughts—such as stress, worry, fear, anger and unforgiveness—actually cause damage to the brain. Chemicals are released into the brain, causing chaos and damage. Those toxic thoughts can cause a loss of sleep or of the ability to do your job right, physical illness and more." Be careful what you pay attention to with your mind.

Isaiah 43:18 “Do not remember the former things, Nor consider the things of old. 19 Behold, I will do a new thing, Now it shall spring forth; Shall you not know it? I will even make a road in the wilderness And rivers in the desert.

Stop bringing back negative memories, God is set to do something new with your life. Your thoughts can affect your health, can cause damages that may seem harmless until later. Someone cheated you or say negative things about you? You can choose your response, but majorly, use God's word.
