“ His strength lay in the simple straight-forwardness of a manly character imbued with the traditions of a sturdy Scottish Christianity. His was a healthy, energetic, and practical evangelicalism, and his manner of proclaiming it appealed to all, from the unlettered peasant to the philosophical or theological specialist. The fact that all over Scotland, and by people of all denominations, he was familiarly and affectionately called 'Cairns of Berwick,' even after he was college principal, of itself marks a deep and unique influence. ”
