His insight into the human heart was marvelous; and in the line of close experimental preaching, he has not had his equal since the days of President Edwards.

He put the impress of his powerful personality on a thousand ministers who graduated from Princeton Seminary.
In his lecture-desk and in the pulpit he was simplicity itself.

His sermons were like the waters of Lake George, so pellucid that you could see every bright pebble far down in the depths; a child could comprehend him, yet a sage be instructed by him.

His best discourses were extemporaneous, and he had very little gesture, except with his forefinger, which he used to place under his chin, and sometimes against his nose in a very peculiar manner.

With a clear piping voice and colloquial style he held his audience in rapt attention, disdaining all the tricks of sensational oratory.
