Context Matters: Righteous Deeds Are Like Filthy Rags

Perhaps you’ve heard that all our righteous deeds are like filthy rags before God. You’ve been taught that God looks at our works and sees something unclean, a pitiful offering not worthy of his attention.

This phrase is often used to urge sinners to embrace Jesus’s work instead of their own for salvation. But is this a correct use of Isaiah’s words? When we learn to read the Bible as a book and not a loose collection of verses and phrases, we’ll see that some familiar sayings take on different meanings than we’ve always assumed.

No Salvation by Works

This memorable phrase comes from Isaiah 64.

We have all become like one who is unclean,
and all our righteous deeds are like a polluted garment.
We all fade like a leaf,
and our iniquities, like the wind, take us away. (Isaiah 64:6)

I often hear this verse cited to emphasize the emptiness of pursuing salvation by works. The speaker usually comments on how the “polluted garment” may be the Old Testament version of a menstrual cloth—a vivid and effective image. (In my memory, this was an ingredient in the first presentation of the gospel to which I responded!)

The problem, as you may have guessed, is that this verse is often pulled out of context. And when that happens with this particular phrase, young disciples may be left questioning their efforts to obey God. If God views our deeds as bloody rags, why should we try to do anything righteous?

The Meaning of “Righteous”

How could God hate righteous deeds? We only need to look at the surrounding verses to answer this question.

You meet him who joyfully works righteousness,
those who remember you in your ways.
Behold, you were angry, and we sinned;
in our sins we have been a long time, and shall we be saved? (Isaiah 64:5)

The first clause in verse 5 shows that God is not against every attempt at righteousness. Further, this helps us understand that the “righteousness” in Isaiah 64:5 cannot be the same as the “righteous deeds” in Isaiah 64:6. God cannot embrace what he calls unclean.

The “righteous deeds” of verse 6 must be ceremonial tasks (or something similar) done by those who have been in their sins a long time (Isaiah 64:5–6). God hates these deeds because they are not righteous at all.

God Our Father

Another key observation about this passage is how the Lord is being addressed. Yes, the people have sinned and turned away, but the prophet (on behalf of the people) is calling on God as “Father.” (This shows up twice in Isaiah 63:16, and also in Isaiah 64:8.)

The rebellion of God’s people can be so great that “righteous deeds” are like polluted garments. This would not be a surprise to Isaiah’s audience, as it formed the spine of his argument in Isaiah 1:10–17. God wanted offerings, incense, and assemblies to stop because the people did them in vain, with their hands full of blood. Going through the motions without love for the Lord is worthless.

God’s people were privileged to call him “Father,” and as their father he wanted their whole-hearted worship. Offering disjointed obedience to the Lord after being seduced by sin is offensive to the One who has been compassionate and merciful (see Isaiah 63:7–14).

In the modern church, the phrase about righteous deeds being like filthy rags is often used to persuade unbelievers. But in the context of Isaiah 64, God’s people are in view. Unlike unbelievers, they knew what righteous deeds were, but they carried them out with cold hearts.

The Dangers of Sin

There are several passages that could be used to instruct unbelievers about salvation by faith alone. That is a glorious truth, and the church should teach it! But we need not resort to pulling this colorful simile out of context to make the point.

The sobering truth of this passage is that God’s people can be deluded. We can chase after sin so much that our attempts to worship and glorify God are offensive to him.
