When the devil robs you of your peace, try meditating on the Word of God. Below is a list of helpful references. Look them up and record its promise. You may want to personalize it by changing “you” to “me” (See example in Joshua 1:5-9). You may find that some of the references have multiple reasons that prompt peace in your heart.
Joshua 1:5-9—The Lord my God is with me wherever I go
2 Corinthians 1:3-4
For more benefit, write each promise on different sizes and shapes of paper and tape them all over the house (kitchen cabinets, bathroom mirror, etc.) Feast your eyes on God’s promises of peace throughout your day.
