Charles H. Spurgeon on Psalms 119:37

Turn away mine eyes from beholding vanity. It may seem strange prayer of David, to say, "Turn away mine eyes from seeing vanity; "as though God meddled with our looking; or that we had not power in selves to cast our eyes upon what objects we list. But is it not, that we delight in, we delight to look upon? and what we love, we love to seeing? and so to pray to God, that our eyes may not see vanity; is as much as to pray for grace, that we be not in love with vanity. For, vanity hath of itself so graceful an aspect, that it is not for a natural man to leave looking upon it; unless the fairer aspect of God's grace draw our eyes from vanity, to look upon itself; which will always naturally looking upon the fairest. And as David here makes his prayer in the particular, against temptations of prosperity, so Christ teacheth us to make prayer in the general, against the temptations, both of prosperity adversity, and very justly. For many can bear the temptations of one who are quickly overcome by temptations of the other kind. So David could bear persecution without murmuring, but when he came to prosperity could not turn away his eyes from vanity. Sir Richard Baker.
