Isaiah Lessons

Filthy Rags
—Isaiah 64:4-9

The statement, "All our righteousness is like filthy rags", is found in the middle of a Biblical poem in Isaiah (Isa 64:4-9). The saying has caused a deep struggle in many hearts. Does the statement mean that it's pointless to do righteous deeds and they have no value in God's eyes? No, it doesn’t.

In this study we put the "filthy rags" statement into context, looking at other statements in Isaiah to see that true righteousness is not "filthy rags".

1 The kingdom of Christ is upheld with righteousness

A theme of Isaiah is the promise of the coming Messiah (or Christ), and one of his marks is righteousness. "Behold I lay in Zion a stone... and I will make justice the measuring line, and righteousness the level" (Isa 28:16-17). Righteousness is the measure used to lay the very foundation of God’s kingdom.

"A child will be born to us, a son will be given to us, and the government will rest on his shoulders... on the throne of David and over his kingdom, to establish it and uphold it with justice and righteousness..." (Isa 9:6-7, see 59:17). Righteousness is the principle by which the Messiah reigns.

Now if we live by this principle and our King’s example, will God repudiate our righteousness as filthy rags? How can Christ-like righteousness be filthy rags?

2 God calls us to do good

A recurring feature of Isaiah is the pleading of the Lord for his people to give up their evil and turn back to righteous living. The Lord says, "Wash yourselves, make yourselves clean, take away from before my eyes the evil of your deeds. Cease to do evil, learn to do good" (Isa 1:16-17). The passage goes on to say that if the people do this willingly and obediently, they will be rewarded and blessed (Isa 1:18-20).

Here’s another example: "Thus says the Lord, Preserve justice and do righteousness... How blessed is the man who does this..." (Isa 56:1-2). How can that be "filthy rags"?

3 God values righteous deeds

God names some of the deeds he delights in: "...to share your bread with the hungry, and bring the homeless poor into your house, when you see the naked to clothe him..." (Isa 58:7). That's doing what God values, not what God despises as filthy rags.

note In the book of Revelation, the bride of Christ was "given fine linen in which to clothe herself, linen bright and clean." What a contrast to filthy rags! And what does this fine linen represent? "The fine linen is the righteous acts of the saints" (Rev 19:7-9).

So the Lord’s response is positive to a humble and upright person, zealous for the way of the Lord. God has covenanted through Christ that "sin shall be taken away" (Isa 27:9, Rom 11:26). When God by his grace, and by the virtue of Christ and his sacrifice, bestows his gift of forgiveness on those who obey him, then God has made them righteous. They should not then say, "All our righteousness is like filthy rags" but rather "I am honoured in the sight of the Lord and God is my strength" (Isa 49:5).

4 But Judah’s righteousness was like filthy rags

The first chapter of Isaiah clarifies God’s reason for rejecting as filthy rags the righteousness of his people in Judah and Jerusalem. They were "alas a sinful nation" and a rebellious people (Isa 1:4-5). They are likened to Sodom and Gomorrah (Isa 1:10-11). Yet they offered to God multiplied sacrifices and prayers (Isa 1:11-15). "How the faithful city has become a harlot, she who was full of justice! Righteousness once lodged in her" (Isa 1:21).

God once was delighted with the people, but now he is disappointed. They have become two-faced. Whilst they continued to worship, they also continued to do evil. The Lord repudiated their false righteousness as filthy rags —or as he puts it in another metaphor here, "Your silver has become dross" (Isa 1:22).

So hypocrites who pretend to worship God while deliberately practicing evil, thinking they can fool the Lord, are the ones whose righteousness is like filthy rags. Their righteousness is soiled by their own unrepented sins or the sins of those around them which they tolerate.

We come to understand therefore, that when Isaiah says, "All our righteousness is like filthy rags" he is speaking on behalf of the nation, an apostate people in decline —not on behalf of those who who turn to God and his Christ for salvation and seek to follow his righteousness (Isa 45:22-25, Isa 55:6-12).
