 
I am leaving you with a gift—peace of mind and heart. And the peace I give is a gift the world cannot give. So don’t be troubled or afraid.
John 14:27 NLT
The Peace of Christ is a rest and repose of the heart that knocks out all disturbing and disruptive forces which would steal our fulfillment in Christ. Peace is an deep, inner sense of contentment supplied by God that transcends our everyday troubles.
Christ’s peace pervades our beings when we hold steady trusting the faithfulness of our heavenly Father. Peace is the fruit of faith: the serenity of heart that comes in trusting God irrespective of struggles and temptations of this life. The world, the flesh, and devil are our soul’s enemies trying to steal our contentment in Christ, but Christ is greater.
We can receive Christ’s peace for he is the Prince of Peace (Isa. 9:6) into the deepest recesses of our spirits. We have peace with God through faith in his shed blood (Rom. 5:1), which establishes peace with others (Eph. 2:14), while freeing us to trust his peace (Isa. 26:3), and as a result, we can now walk in peace in the midst of our greatest needs (Phil. 4:7).
In all the rush of life, in working for our living, in all conditions of bodily life, wherever God engineers our circumstances—“My peaceâ€; the imperturbable, inviolable peace of Jesus imparted to us in every detail of our lives. “Your life is hid with Christ in God.†Have we allowed the wonder of it to enwrap us round and soak us through until we begin to realise the ample room there is to grow there? “The secret place of the Most High,†absolutely secure and safe.
