Charles H. Spurgeon on Psalms 119:3

They also do no iniquity. If it be demanded here, How is it that they who walk in God's ways work no iniquity? Is there any man who lives, and sins not? And if they be not without sin, how then are they to be blessed? The answer is, as the apostle says of our knowledge, "We know but in part": so is it true of our felicity on earth, we are blessed but in a part. It is the happiness of angels that they never sinned; it is the happiness of triumphant saints, that albeit they have been sinners, yet now they sin no more; but the happiness of saints militant is, that our sins are forgiven us; and that albeit sin remains in us, yet it reigns not over us; it is done in us, but not by our allowance: "I do the evil which I would not." "Not I, but sin that dwells in me, "Romans 7:17.

To the doing of iniquity, these three things must concur; first, a purpose to do it; next, a delight in doing it; thirdly, a continuance in it; which three in God's children never concur; for in sins done in them by the old man, the new man makes his exceptions and protestations against them. It is not I, says he; and so far is he from delighting in them, that rather his soul is grieved with them; even as Lot, dwelling among the Sodomites, was vexed by hearing and seeing their unrighteous deeds. In a word, the children of God are rather sufferers of sin against their wills than actors of it with their wills: like men spiritually oppressed by the power of their enemy; for which they sigh and cry unto God. "Miserable man that I am! who shall deliver me from the body of this death?" And in this sense it is that the apostle saith, "He who is born of God sinneth not" (1 John 3:9). William Cowper.
