DR KENNEDY, in his “Apostle of the North,” tells an interesting story of Dr Macdonald, Ferintosh, that has a lesson for many. Mr Macdonald, as he then was, had been anxiously preparing a sermon on a very difficult text, when at length on the Saturday morning he was compelled to lay all his preparation aside, and think of a different subject from that which he had so carefully studied. He wrote a few hurried notes, started for one of the distant preaching stations included in the Berriedale Mission in Caithness, and reached late at night the house of Marcus Gunn, a noted Christian. “I am very glad to see you,” said Marcus, as he met Mr Macdonald at the door. With more than his wonted warmth of manner, he repeated the salutation as they entered the house together, and again after they were seated. “There is surely some reason,” said Mr Macdonald, “why you are so glad to see me to-night.” “There is,” was the reply, “I was very anxious about you. I was thinking of you last night. I thought that you were attempting to rise up to the clouds for manna to give to your people, and that you tried in vain; that you then at last began to look for it on the ground, where the Lord had laid it, and there you found it. And if I am not greatly mistaken, your text to-morrow should be John vi. 37.” This was the very passage to which Mr Macdonald’s mind had been directed when he was compelled to give up his preparation on the difficult text.
