His fame as a pulpit orator had now travelled from Maidenkirk to John o' Groats, and it could not be expected that he should be left in a secluded country parish. In Glasgow, the Tron parish church had become vacant, and Chalmers was suggested as successor to Dr. Macgill. It was easy for the anti-evangelical party to ridicule the idea of bringing a madman to such a place; but a deputation from the Town Council, who were patrons of the church, went to hear him preach. On the Sunday in question he preached, at Bendochy, a funeral sermon on Mr. Honey, a young minister whose fatal illness had been brought on by his exertions in saving from shipwreck seven exhausted sailors, whom, one by one, he bore from their stranded vessel to the shore. The impression of that sermon was overpowering. In spite of the opposition of the Duke of Montrose, Sir Islay Campbell, the Lord Provost, and the College, Chalmers received from the Town Council a presentation to the Tron, and, after considerable hesitation, accepted it. It was a great wrench to tear himself from Kilmany, which he loved and admired so greatly, and from the people that were dear to him as his own children. All his life, Fife, and especially Kilmany, continued thus dear. On his way to Glasgow he had occasion to climb the Calton Hill in Edinburgh, and the sight of Norman Law, which was visible from the windows of the manse of Kilmany, quite overcame him. 'Oh! with what vivid remembrance can I wander in thought over all its farms and all its families, and dwell on the kind and simple affection of its people, till the contemplation becomes too bitter for my endurance.'
It was no less a trial to leave the work which was now advancing so hopefully in the parish. But he could not be insensible to the claims of such a city as Glasgow, and the boundless field for usefulness it afforded. And so, in great humility, and in great fear lest he should be giving an undue preference to intellect and culture over poverty and obscurity, he accepted the call. He preached a most impressive farewell sermon on 9th July 1815, which concluded with these words: 'Be assured, my brethren, that after the dear and the much-loved scenery of this peaceful vale has disappeared from my eye, the people who live in it shall retain a warm and an ever-enduring place in my memory; and this mortal body must be stretched on the bed of death ere the heart that now animates it can resign its exercise of longing after you, and praying for you that you may so receive Christ Jesus, and so walk in Him, and so hold fast the things you have gotten, and so prove that the labour I have had among you has not been in vain, that when the sound of the last trumpet awakens us, these eyes which are now bathed in tears may open upon a scene of eternal blessedness, and we, my brethren, whom the providence of God has withdrawn for a little time from each other, may on that day be found side by side at the right hand of the everlasting throne.'
When we compare Chalmers as he came to Kilmany and as he left it, we find much that remains the same, and much that has been changed or modified.
Remaining the same, we find his singularly energetic, forceful nature; his high integrity and kindliness of heart, as it constantly streamed out towards his family, his friends, and his flock; his eager desire for the welfare of his people, for their advancement and elevation in all that he counted good, pure, and noble; his indomitable energy of purpose and fearless contending for right and truth; his passionate intensity of conviction, rolling itself out in whirlwinds and tempests of eloquence, that swept all before it. The great change which he has undergone has not destroyed these fundamental elements of character.
