Let no corrupt communication proceed out of your mouth, but that which is good.
How you communicate should reflect who you are as a son or daughter of God. Clean and intelligent language is evidence of a bright and wholesome mind. Good language that uplifts, encourages, and compliments others invites the Spirit to be with you. Our words, like our deeds, should be filled with faith, hope, and charity.
Choose friends who use good language. Help others improve their language by your example. Be willing to politely walk away or change the subject when those around you use inappropriate language.
Speak kindly and positively about others. Choose not to insult others or put them down, even in joking. Avoid gossip of any kind, and avoid speaking in anger. When you are tempted to say harsh or hurtful things, leave them unsaid.
Always use the names of God and Jesus Christ with reverence and respect. Misusing the names of Deity is a sin. When you pray, address your Father in Heaven in reverent and respectful language. The Savior used such respectful language in the Lord’s Prayer (see Matthew 6:9–12).
Do not use profane, vulgar, or crude language or gestures, and do not tell jokes or stories about immoral actions. These are offensive to God and to others.
Remember that these standards for your use of language apply to all forms of communication, including texting on a cell phone or communicating on the Internet.
If you have developed the habit of using language that is not in keeping with these standards—such as swearing, mocking, gossiping, or speaking in anger to others—you can change. Pray for help. Ask your family and friends to support you in your desire to use good language.
