And let the peace of God rule in your hearts, to which also you were called in one body; and be thankful. Colossians 3:15
Aand the peace of God, which surpasses all understanding, will guard your hearts and minds through Christ Jesus. Philippians 4:7
Once we have Peace with God, then we can enjoy the Peace of God. This could be called emotional peace. God wants us to have a peace that surpasses all understanding that can only come after we get the Peace of God.
Are you allowing the peace of God to rule your heart? If not why not?
