Root

The mind is a constant interpreter of what we hear and experience. My ears hear, "Wow, that is some really pink nail polish." My mind interprets, That is the ugliest color in the world; you are ugly. I experience a sassy, yelling at others golden head and my mind interprets, You're doing a horrible job as a mother.
The mind is a battle field between truth and lies, good and evil. Satan is constantly trying to tempt, distract or attack us and it starts in the mind. The mind interprets based on a primary emotion or fear that often finds its root in an early experience. While it may be interesting to pinpoint the experience that sprouted all this (facing it, forgiving and begin healing), what's more important is knowing the root emotion. In the case above, the emotion is fear of conditional acceptance. When you can pinpoint the primary fear or emotion, you hold it up to the flawless Word of God and speak truth.

• He chose me in Christ before the foundation of the world that I should be holy and blameless before Him. (Ephesians 1:4)
• See what kind of love the Father has given to me, that I should be called a child of God; and so I am. (1 John 3:1a)
• I can go to Jesus and He will never reject me. (John 6:37) 

To believe anything counter to God's Word is to believe a lie and fall victim to Satan's attack.
What emotional language does your brain interpret? Spend time identifying the root emotion or fear and then search God's Word for the truth of the matter. I love these truth statements from Neil Anderson.
