So all affection, our whole kindred, are severed from us; lest under cover of duty any believer should be exposed to offence. If, He says, he be united to thee as close as is thy hand, or foot, or eye, and is useful to thee, anxious and quick to discern, and yet causes thee offence, and is by the unmeetness of his behaviour drawling thee into hell; it is better for thee that thou lack his kindred, and his profitableness to thee, than that whilst thou seekest to gain thy kindred or friends, thou shouldest have cause of failings. For every believer knows what is doing him harm, what troubles and tempts him, for it is better to lead a solitary life, than to lose eternal life, in order to have the things necessary for this present life.
