I’d always worried about the meaning of Christ’s phrase: “sin no more.” Only in the last few years have I come to a settled understanding closer to what the Lord meant by it:

Afterward Jesus found him in the temple and said to him, “See, you are well! Sin no more, that nothing worse may happen to you.” John 5:14 English Standard Version (ESV)

Calvin has many words to say about this verse. Here are a few of them:

After these things Jesus found him. …When he charges him, sin no more, he does not enjoin him to be free from all sin, but speaks comparatively as to his former life; for Christ exhorts him henceforth to repent, and not to do as he had done before.

Lest something worse befall thee. …When we are incessantly pressed down by new afflictions, we ought to trace this to our obstinacy…There is no reason to wonder, therefore, if God makes use of severer punishment to bruise us…when moderate punishment is of no avail; for it is proper that they who will not endure to be corrected should be bruised by strokes.

…Indeed, the roots of vices are too deep in us to be capable of being torn out in a single day, or in a few days; and the cure of the diseases of the soul is too difficult to be effected by remedies applied for a short time.

Calvin’s entire commentary on the verse implies, among other things, that the man was made well through God’s grace, and not only that, but raised from the dead to new life in Him.

Recently, while researching a blog post on Idols, concerning a passage in Matthew:

“No one can serve two masters, for either he will hate the one and love the other, or he will be devoted to the one and despise the other. You cannot serve God and money [or possessions].” Matthew 6:24 (ESV)

I ran across this statement by Calvin:

…It is, no doubt, true, that believers themselves are never so perfectly devoted to obedience to God, as not to be withdrawn from it [i.e., obedience] by the sinful desires of the flesh. But as they groan under this wretched bondage, and are dissatisfied with themselves, and give nothing more than an unwilling and reluctant service to the flesh, they are not said to serve two masters.

For their desires and exertions are approved by the Lord, as if they rendered to him a perfect obedience. But this passage reproves the hypocrisy of those who flatter themselves in their vices, as if they could reconcile light and darkness.

This is a deep and encouraging statement about the sanctification process that God performs in His own to bring about their maturity in following His Son. And He brooks no counterfeit.

Sanctification leads to a maturity outlined by the Apostle Paul in his letter to the Galatian church:

Now the works of the flesh are evident: sexual immorality, impurity, sensuality, idolatry, sorcery, enmity, strife, jealousy, fits of anger, rivalries, dissensions, divisions, envy, drunkenness, orgies, and things like these. I warn you, as I warned you before, that those who do such things will not inherit the kingdom of God.

But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, self-control; against such things there is no law. Galatians 5:19-23 (ESV)

To this passage, Calvin says:

But the fruit of the Spirit. In the former part of the description he condemned the whole nature of man as producing nothing but evil and worthless fruits. He now informs us that all virtues, all proper and well-regulated affections, proceed from the Spirit, that is, from the grace of God, and the renewed nature which we derive from Christ. As if he had said, “Nothing but what is evil comes from man; nothing good comes but from the Holy Spirit.”

So let’s lay aside the deeds of the flesh and press on to do good works and exhibit fruit of the Spirit.
