'It is the greatest unkindness that can be showed to a friend, to adventure the complaining, bleeding, and grieving of his soul upon a light and a slight occasion. So it is the greatest unkindness that can be showed to God, Christ, and the Spirit, for a soul to put God upon complaining, Christ upon bleeding, and the Spirit upon grieving, by yielding to little sins. Therefore when Satan says it is but a little one, do thou answer, that oftentimes there is the greatest unkindness showed to God's glorious majesty, in the acting of the least folly, and therefore thou wilt not displease thy best and greatest friend, by yielding to his greatest enemy.'
Thomas Brooks, Precious Remedies Against Satan's Devices, p.41.
