More heat than light

Tue 17 Aug 1762: We rode to Northampton, the next day to Sundon, and on Thursday, 19, to London. Friday, 20. As I expected, the sower of tares had not been idle during my five months' absence; but I believe great part of his work was undone in one hour, when we met at West-Street. I pointed out to those who had more heat than light, the snares which they had well nigh fallen into. And hitherto they were of an humble teachable spirit. So for the present the snare was broken.
