The Lord kept saying within me, "Since none better qualified can be got, rise and offer yourself!" Almost overpowering was the impulse to answer aloud, "Here am I, send me." But I was dreadfully afraid of mistaking my mere human emotions for the will of God. So I resolved to make it a subject of close deliberation and prayer for a few days longer, and to look at the proposal from every possible aspect. Besides, I was keenly solicitous about the effect upon the hundreds of young people and others, now attached to all my Classes and Meetings; and yet I felt a growing assurance that this was the call of God to His servant, and that He who was willing to employ me in the work abroad, was both able and willing to provide for the on-carrying of my work at home. My medical studies, as well as my literary and divinity training, had specially qualified me in some ways for the Foreign field, and from every aspect at which I could look the whole facts in the face, the voice within me sounded like a voice from God.
It was under good Dr. Bates of West Campbell Street that I had begun my career in Glasgow--receiving £25 per annum for district visitation in connection with his Congregation, along with instruction under Mr. Hislop and his staff in the Free Church Normal Seminary--and oh, how Dr. Bates did rejoice, and even weep for joy, when I called on him, and offered myself for the New Hebrides Mission! I returned to my lodging with a lighter heart than I had for sometime enjoyed, feeling that nothing so clears the vision, and lifts up the life, as a decision to move forward in what you know to be entirely the will of the Lord. I said to my fellow-student, Joseph Copeland, who had chummed with me all through our course at college, "I have been away signing my banishment" (a rather trifling way of talk for such an occasion). "I have offered myself as a Missionary for the New Hebrides."
After a long and silent meditation, in which he seemed lost in far-wandering thoughts, his answer was, "If they will accept of me, I am also resolved to go!"
I said, "Will you write the Convener to that effect, or let me do so?"
A few minutes later his letter of offer was in the post-office. Next morning Dr. Bates called upon us, early, and after a long conversation, commended us and our future work to the Lord God in fervent prayer. At a meeting of the Foreign Missions Committee, held immediately thereafter, both were, after due deliberation, formally accepted, on condition that we passed successfully the usual examinations required of candidates for the Ministry. And for the next twelve months we were placed under a special committee for advice as to medical experience, acquaintance with the rudiments of trades, and anything else which might be thought useful to us in the Foreign field.
