What are the circumstances amid which the modern Church is placed? The Christian believer in our day is confronted with stupendous difficulties. Look at the present field on which our Christian warfare is to be waged. When the European war broke out I was staying at a quiet seaside village, from which I could see the soft green beauty of the mountains which encircle the English lakes. On the morning that war was proclaimed I felt as though some venerable and majestic temple had suddenly crumbled into dust. One of my most intimate friends, a noble German, was staying in my home, and we both felt as though some devil of mischief and disaster had toppled human affairs into confusion. The quiet sequence of human progress seemed to have been smashed at a stroke. The nations drew apart, and gulfs of isolation yawned between them, and down the gulfs there swept the cruel shrieking blasts of racial hatred and antipathy. Holy ministries which had been leagued in sacred fellowship were wrenched asunder. Spiritual communions which had been sweet and welcome curdled in the biting blast of resentment. The work of the Kingdom of our Lord was smitten as by an enemy; ploughshares were beaten into swords; pruning-hooks were transformed into spears; and instead of the fir and the myrtle-tree there sprang up the thorns and the briars. And then, to crown our difficulties, the red fury of war leaped into countries where our missionaries are proclaiming the gospel of peace, and the passion of battle began to burn where they are telling the story of the passion of Calvary, that holy passion of sacrifice which brought to the whole world redemption from sin, and reconciliation with God, and the promise of the life that now is, and of that which is to come. Our immediate circumstances do not offer the soldiers of Jesus an easy parade ground where we can just loll and sing our lilting songs; they rather offer us a fearfully rugged and broken field which demands as heroic and chivalrous virtues as ever clothed a child of God. What shall we do? Is it the hour for craven fear or for a noble courage? What shall we do on our mission fields? Shall we cry "forward," or shall we sound the depressing and despairing note of retreat? Shall we throw up the sponge, or shall we, in the spirit of unprecedented sacrifice, march forward in our campaign, and endure hardness as good soldiers of Jesus Christ?
