What the Bible Says About Cursing

Cursing, in the moral sense the New Testament addresses, is the use of the tongue to wound, demean, or call down evil upon others. Scripture takes our words with great seriousness, for they reveal the heart and shape the lives of those who hear them. James names the inconsistency directly in James 3:10: "From the same mouth come blessing and cursing. My brothers, these things ought not to be so." The same lips that praise God should never be turned to curse people made in his image. Proverbs 18:21 weighs the stakes: "Death and life are in the power of the tongue," reminding us that speech can heal or destroy. The most striking biblical teaching is Jesus' command to reverse the instinct toward cursing. In Matthew 5:44 he says, "Love your enemies and pray for those who persecute you," and in Luke 6:28 he adds, "Bless those who curse you, pray for those who abuse you." Paul echoes this radical grace in Romans 12:14: "Bless those who persecute you; bless and do not curse them." Rather than answering insult with insult, the believer is called to break the cycle of hostility with blessing. This ethic also shapes everyday speech. Ephesians 4:29 instructs, "Let no corrupting talk come out of your mouths, but only such as is good for building up... that it may give grace to those who hear." The Old Testament had already warned that cursing recoils upon the one who loves it; Psalm 109:17 says, "He loved to curse; let curses come upon him!" The Bible's call is therefore consistent and clear: surrender the tongue to God, refuse to curse even those who wrong you, and let every word become a channel of grace and blessing rather than harm.
