Peace I leave with you, my peace I give unto you. John 14:27
Peace in the usual sense of the word is hardly descriptive of the life of a junior hospital doctor. Demands for our services come thick and fast and often all at once. The ubiquitous 'bleep' intrudes on meals, conversations, relaxation, sleep and everything else we do. But Jesus promises his peace to reign in our hearts, a peace like no other peace, independent of circumstances and in spite of all that would harass us.
What is it? It is peace with God, the peace of forgiven sin and reconciliation with him: 'justified by faith we have peace with God through our Lord Jesus Christ' (Rom 5:1). Nothing can equal or disturb the peace that springs from his free saving grace.
He tells us, too, that since we are at peace with God, and trusting in him, his resources are available for every need and all eventualities. He wants to garrison our hearts all day and every day from fear and every anxious thought. 'You will keep in perfect peace him whose mind is steadfast because he trusts in you' (Is 26:3 NIV).
But we have a part to play. Our Master not only assures us, he commands us, 'Let not your hearts be troubled, neither let them be afraid' (Jn 14:27). 'Let the peace of Christ rule in your hearts, to which indeed you were called' (Col 3:15).
Peace, perfect peace, in this dark world on sin?
The blood of Jesus whispers peace within.
Peace, perfect peace, by thronging duties pressed?
To do the will of Jesus, this is rest.
Peace, perfect peace, our future all unknown?
Jesus we know, and he is on the throne.
