Charles H. Spurgeon on Psalms 119:36

Incline my heart unto thy testimonies, and not to covetousness. We must be convinced that covetousness, I mean that our covetousness, is vice; for it holds something of a virtue, of frugality, which is not to that which one hath: and this makes us entertain thoughts that it is no vice; and we often say that it is good to be a little worldly; a little covetousness we like well; which shows that we do not indeed and in heart, hold it to be a sin. For if sin be naught, a little of sin cannot be good. As good say, a little poison were good, so it be not too much. And so we find, that men will rate at their children for spending, and are ready to turn them of doors, if they be given unto waste; but if they be near and pinching then we like that too much; and I scarce know a man who doth use to call upon his children that they spare not, save not. I know youth is rather addicted the other way, and is more subject to waste and consume, by that the natural heat is quick and active in them; and therefore there is more fear and danger that they prove prodigal and turn and therefore the more may be said and done that way to youth. But the thing I press is, that in case we see our children in their youth to begin to be covetous and worldly, we call them good husbands, and are but too to see it so, and are too much pleased with them for it. Little do think that worldliness is a most guilty sin in respect of God, and hurtful in respect of men. Hark what the word of God saith of it, Ephesians 5:5: It is idolatry, and idolatry is the first sin of the first table. It is the root of all evils, 1 Timothy 6:10. There is no evil but a worldly man do it to save his purse. Thus David: "Incline my heart unto thy testimonies, and not to covetousness": he saith not, this or that testimony, but (as including all the laws of God) he saith "testimonies"; to show us covetousness draws us away, not from some only, but from all God's commandments. So St. Paul: where covetousness is, there are "many lusts, " 1 Timothy 6:9, and "many sorrows, "1 Timothy 6:10. "It drowns men in perdition and destruction, "1 Timothy 6:9. And the Greek word signifies such a drowning as is almost past all hope and recovery. It is the bane all society: men cry out of it, because they would have none covetous, rich but themselves. A hater he is of mankind; he hates all poor, they would beg something of him; and all rich, because they have which he would have. A covetous man would have all that all have. Thus speaks a noble father (Chrysostom). Such believe not the word, they trust neither nor man. For he that trusts not God, cannot trust man. It robs God that confidence we should have in him, and dependence we owe unto him it turns a man from all the commandments. Hence the prophet prays God to turn his heart to his commandments, "and not to covetousness." For not only we ought not, but as the phrase is, "we cannot serve God mammon, "Luke 16:13.
