And the peace of God, which transcends all understanding, will guard your hearts and your minds in Christ Jesus.—Philippians 4:7 (NIV)
If you find yourself thinking negatively or being pessimistic about a situation, say this verse slowly. Take each word into your heart. Contemplate the vast peace of God, flowing through you, guarding your heart, replacing negative thoughts with positive ones and leaving you calm and relaxed.
Heavenly Father, because of You and Your word, unhealthy thoughts lose the power to control me.
