In merely stating Tholuck's definitions, however, we do not measure out justice to him. He must not be tested by any special department of labor, but by the spirit and totality of his service. In this light he is a remarkable personage, and his work is entitled to our highest eulogium. With him, Christ is not merely a person to be apprehended by the mind, but a Saviour to be received into the heart and henceforth to be a living power of the soul. He must be accepted by Christian faith, and the heart must undergo the transforming power of his Spirit. Without this preparation, all progress in science is but the worship of nature, and man, at the close of life, looks back upon a path of error and forth into a world of darkness. "Tholuck has this characteristic," says one of his countrymen, "he cannot be classified; he belongs to no particular theological direction, because he belongs to all." This estimate is strictly true. He has gained his greenest laurels in exegesis; and his commentaries on Psalms, the Sermon on the Mount, Gospel of John, and Epistles to the Romans and Hebrews, have already taken their places in the theological libraries of English and American divines. But he has asked himself the question, "What can I do to lessen the hold which Rationalism has upon my country?" And he has given the answer by his life-career. All his productions centre in that thought, and it is not the least of his service that he has written sketches of the old Reformation theologians, as an incentive to the restoration of their spirit. It is not easy to estimate the benefit which his _Sin and Redemption_ has conferred upon the young men of Germany. The Baron von Kottwitz is the real personage represented by the patriarch. Let us hear this venerable saint as he stands upon the border of the grave and anticipates a bright future for his loved church and country. His words are the key to Tholuck's life, and reveal the bright hope which burned within him ever since the day when he was welcomed to Halle by the hisses and threats of the Rationalists.
