The thought that he was thus influencing others for good, that he was leading men and women into paths of sure happiness brought him a spiritual calm and peace such as the gratification of worldly ambitions had never given him.  More and more he became convinced it was the only work worth doing.  The strong love for his fellowmen, the desire to help those in need and to make them happier which had always been such a pronounced characteristic, had set him more than once to thinking of the ministry as a life work.  Indeed, ever since that childish sermon, with the big gray rock as a pulpit, it had been in his mind, sometimes dormant, breaking out again into strong feeling when for a moment he stood on some hilltop of life and took in its fullest, grandest meaning, or in the dark valley of suffering and sorrow held close communion with God and saw the beauty of serving Him by serving his fellowmen.  That the inclination was with him is shown by the fact that when he was admitted to the bar in Albany in 1865, he had a Greek Testament in his pocket.

As soon as his means permitted after the war, he gathered a valuable theological library, sending to Germany for a number of the books.  In 1875, when he was admitted to practice in the Supreme Court of the United States, he delivered an address that same evening in Washington on the “Curriculum of the School of the Prophets in Ancient Israel.”  From all parts of the Old World he gathered photographs of ancient manuscripts and sacred places, and kept up a correspondence with many professors and explorers interested in these topics.  He lectured in schools and colleges on archaeological subjects, with illustrations prepared by himself.

It is not to be wondered that with his keen mind and his gift of oratory the law tempted him at first to turn aside from the promptings of the inner spirit.  Nor is it to be wondered that even when inclination led strongly he still hesitated.  It was no light thing for a man past thirty to throw aside a profession in which he had already made an enviable reputation and take up a new lifework.  With two small children depending upon him, it was a question for still more serious study.

But gradually circumstances shaped his course.  In 1874, he married Miss Sarah F. Sanborn whom he had met in his mission work.  She was of a wealthy family of Newton Centre, the seat of the Newton Theological Seminary.  One of the intimate friends of the family was the Rev. Alvah Hovey, D.D., President of the Seminary.  Thus while inclination pulled one way and common sense pulled the other, adding as a final argument that he had no opportunity to study for the ministry, he was thrown among the very people who made it difficult not to study theology.  Troubled in mind he sought Dr. Hovey one day and asked how to decide if “called to the ministry.”  “If people are called to hear you,” was the quick-witted, practical reply of the good doctor.  But still he hesitated.  His law practice, writing, lecturing, claimed part of him; his Sunday School work and lay preaching, a second and evergrowing stronger part.  His law practice became more and more distasteful, his service to the soul needs of others, more and more satisfying.
