Grimshaw himself says, in a letter to Dr. Gillies, author of the "Historical Collections:" "Souls were affected by the word, brought to see their lost estate by nature, and to experience peace through faith in the blood of Jesus. My church began to be crowded, insomuch that many were obliged to stand out of doors. Here, as in many places, it was amazing to see and hear what weeping, roaring, and agony, many people were seized with, at the apprehension of their sinful state and wrath of God. After a season I joined people, such as were truly seeking, or had found the Lord, in society, for meetings and exercises. These meetings are held once a week, about two hours, and are called classes, consisting of about ten or twelve members each. We have much of the Lord's presence among them, and greatly, in consequence, must such meetings conduce to Christian edification."
