Charles H. Spurgeon on Psalms 119:133

Let not any iniquity, etc. True obedience to God is inconsistent with the dominion of any one lust, or corrupt affection. I say, though a man out of some slender and insufficient touch of religion upon his heart, may go right for a while, and do many things gladly; yet that corruption which is indulged, and under the power of which a man lieth, will at length draw him off from God; and therefore no one sin shall have dominion over us. When doth sin reign, or have dominion over us? When we do not endeavour to mortify it, and to cut off the provisions that may feed that lust. Chrysostom's observation is, the apostle does not say, let it not tyrannize over you, but, let it not reign over you; that is, when you suffer it to have a quiet reign in your hearts. Thomas Manton.
