Thomas Boston, Works, 1:634-635:
When we love the godly for their godliness, the saints for their sanctity, we love God in them, and so may conclude, “that every one that loveth him that begat, loveth him also that is begotten of him,” 1 John 5:1. Hypocrites may love saints because of natural relation to them, their obliging conversation, their being of their way or opinion, and the like: but happy those who love them for naked grace in them, that pick the pearl out of the dunghill of many unpleasing things about them, and kindly love them for that.
