I do not need to remind you, I suppose, of the value, as a piece of evidence of the historical veracity of the Gospel story, of this sudden change and complete revolution in the sentiments and emotions of that handful of disciples. What was it that lifted them out of the pit? What was it that revolutionised in a moment their notions of the Cross and of its bearing upon them? What was it that changed downhearted, despondent, and all but apostate, disciples into heroes and martyrs? It was the one fact which Christendom commemorates to-day: the resurrection of Jesus Christ. That was the element, added to the dark potion, which changed it all in a moment into golden flashing light. The resurrection was what made the death of Christ no longer the occasion for the dispersion of His disciples, but bound them to Him with a closer bond. And I venture to say that, unless the first disciples were lunatics, there is no explanation of the changes through which they passed in some eight-and-forty hours, except the supernatural and miraculous fact of the resurrection of Jesus Christ from the dead. That set a light to the thick column of smoke, and made it blaze up a 'pillar of fire.' That changed sorrow into joy. The same death which, before the resurrection, drew a pall of darkness over the heavens, and draped the earth in mourning, by reason of that resurrection which swept away the cloud and brought out the sunshine, became the source of joy. A dead Christ was the Church's despair; a dead and risen Christ is the Church's triumph, because He is 'the Christ that died... and is alive for evermore.' But, more generally, let me remind you how this very same principle, which applies directly and historically to the resurrection of our Lord, may be legitimately expanded so as to cover the whole ground of devout men's sorrows and calamities. Sorrow is the first stage, of which the second and completed stage is transformation into joy. Every thundercloud has a rainbow lying in its depths when the sun smites upon it. Our purest and noblest joys are transformed sorrows. The sorrow of contrite hearts becomes the gladness of pardoned children; the sorrow of bereaved, empty hearts may become the gladness of hearts filled with God; and every grief that stoops upon our path may be, and will be, if we keep near that dear Lord, changed into its own opposite, and become the source of blessedness else unattainable. Every stroke of the bright, sharp ploughshare that goes through the fallow ground, and every dark winter's day of pulverising frost and lashing tempest and howling wind, are represented in the broad acres, waving with the golden grain. All your griefs and mine, brother, if we carry them to the Master, will flash up into gladness and be "turned into joy." II. Still further, another aspect here of the glad life of the true Christian is, that it is a joy founded upon the consciousness that Christ's eye is upon us.
