Quotes from Charles W. Koller

He may not have the eloquence of a ready tongue, but will have that eloquence which is of the heart. His concern in the study will be not merely to prepare sermons, but, even more, to prepare his own heart. And when he preaches it will not be in feeble whispers, but with the spiritual vitality of the prophets and apostles, of whom he is a lineal descendant.
