" The highest of missionary motives is neither obedience to the Great Commission (important as that is), nor love for sinners who are alienated and perishing (strong as that incentive is, especially when we contemplate the wrath of God . . .), but rather zeal—burning and passionate zeal—for the glory of Jesus Christ. . . . Only one imperialism is Christian . . . and that is concern for His Imperial Majesty Jesus Christ, and for the glory of his empire.2 "
