Romans 3:14 describes the speech of people who have turned away from God: their mouths are full of cursing and bitterness. Paul is not describing a few bad moments but a pattern that shows what is going on inside a person. He writes this in his letter to the church in Rome, drawing on a string of Old Testament passages to make his case that every person, Jew and Gentile alike, stands in need of God’s grace.

What Romans 3:14 Means
The phrase “their mouth” points to speech as a window into the heart. Jesus made the same point when he said the mouth speaks out of what fills the heart. Paul’s image is of a mouth so full of cursing that there is no room left for anything else. The word “cursing” refers to words that wish harm or ruin on others, and “bitterness” describes a sour, resentful spirit that poisons relationships over time.
The verse is a diagnosis, not a complete portrait. Paul is quoting Psalm 10:7 and reinforcing his argument from the verses just before it, so the picture is of human nature apart from God’s mercy. It does not promise that every person speaks this way all the time, and it does not say that a person who has been bitter can never change. Its purpose is to show why people need a righteousness that comes from outside themselves.
The Context of Romans 3:14
Paul wrote Romans to a mixed congregation of Jewish and Gentile believers in the city of Rome, probably in the late 50s AD. In the earlier chapters he builds a case that no one can stand before God on the basis of their own goodness. Verses 11 and 12 say that no one understands or seeks God, and verse 13 links human speech to deceit and poison. Verse 14 is the next step in that list, and verses 15 through 17 move from speech to violence and the broken paths people walk.
Read in that setting, the verse is not a random insult aimed at a particular group. It is part of a sweeping argument that closes off any boast of moral superiority. Paul wants his readers to see that the problem is universal, which is why he goes on in Romans 3:21 to speak of a righteousness that comes through faith in Jesus Christ.
Key Phrases in Romans 3:14

This verse calls believers to put away bitterness, wrath, anger, and slander, showing that the attitudes Paul names in Romans 3:14 are ones Christians are expected to lay down by the power of the Spirit.
James 3:9-10
9 With it we bless our God and Father, and with it we curse men, who are made in the image of God. 10 Out of the same mouth comes blessing and cursing. My brothers, these things ought not to be so.

James points out the strange contradiction of blessing God and then cursing people made in his image, which echoes the concern about cursing that Paul raises in Romans 3:14 and calls for speech that is consistent with faith.
A Short Prayer From Romans 3:14
Lord, you see what fills my heart even when my words try to hide it. Forgive me for the cursing I have spoken and for the bitterness I have held onto when I thought I was justified. Cleanse my heart from the inside out, and teach me to speak words that build up rather than tear down. Thank you that your mercy reaches people like me, and help me to receive it and share it with others. Amen.
