and with your feet fitted with the readiness that comes from the gospel of peace. Ephesians 6:15 (NIV)
God is a God of peace and He has already made peace with man through the sacrifice of His Son Jesus. This is the Gospel or Good News of Peace.
Because there’s no peace for the wicked (Isaiah 48:22), the enemy, the wicked one always does all he can to keep us in turmoil, totally without peace. But as we focus on the gospel of peace that announces and affirms that we are reconciled with God in Christ, accepted before Him in love, that God is with us, in us and for us we can walk in peace, in wholeness and victory.
