These were then some of the darkest days of Indian history, the time of the tragedy of the Black Hole of Calcutta, of wanton treachery, of pitiless hate and massacre, and all the miseries of a bloody war. In the midst of these stormy conflicts, Schwartz was much concerned with the indifference which existed in the minds of the natives towards the claims of the Christian religion. Thankful as he felt for the marks of success on many hands, he realized increasingly, as all thoughtful workers must do, the darkness of the heathen mind and how little after all was accomplished. Schwartz was no pessimist; indeed, a careful study of his character gives the refreshing idea of a man of vivacity and hopefulness, strong of faith in God and ultimate victory, comforting himself with the promise of Holy Scripture whenever the difficulties were more than usually severe. With it all, there is the revelation of the sense of self-abasement, the condemnation of the slightest risings of pride and satisfaction which we find in the lowliness of spirit of Thomas à Kempis and other mystics. The mind of the man, too, is manifested so clearly in his letters, which are like little windows enabling us to look into this brave heart. He is writing under date 17th October, 1755, to his old friend and guide, Professor Francke at Halle, and breaks forth into a strain of praise and thanksgiving: “Blessed be the God and Father of our Lord Jesus Christ, the God of all true consolation, salvation, and life, who mercifully and gloriously helpeth us in all trouble! He is a God that delighteth in our life, a God that humbleth that he may exalt us, that maketh us to feel our wretchedness that he may thoroughly save us from it. My soul doth magnify the Lord!
