Charles H. Spurgeon on Psalms 4:2

"Love vanity." Men's affections are according to their principles; and every one loves that most without him which is most suitable to somewhat within him: liking is founded in likeness, and has therefore that word put upon it. It is so in whatsoever we can imagine; whether in temporals or spirituals, as to the things of this life, or of a better. Men's love is according to some working and impression upon their own spirits. And so it is here in the point of vanity; those which are vain persons, they delight in vain things; as children, they love such matters as are most agreeable to their childish dispositions, and as do suit them in that particular. Out of the heart comes all kind of evil. Thomas Horton, 1675.
