No, I know Facebook, Twitter, and other forms of social media weren’t around when the Bible was written, but people were communicating then, and Biblical ideas about communication are needed as much now as when they first appeared.
Consider these:
“…everyone should be quick to listen, slow to speak, and slow to become angry” (James 1:19, NIV) *
“…the prudent hold their tongues.” (Proverbs 10:19b, NIV)
“Do not let any unwholesome talk come out of your mouths, but only what is helpful for building others up according to their needs, that it may benefit those who listen.” (Ephesians 4:29, NIV)
“A gentle answer turns away wrath, but a harsh word stirs up anger.” (Proverbs 15:1, NIV)
“A man finds joy in giving an apt reply–and how good is a timely word!” (Proverbs 15:23, NIV)
“Better a patient man than a warrior, a man who controls his temper than one who takes a city.” (Proverbs 16:32, NIV) (In ancient times, a warrior who “took a city” received all kinds of acclaim and rewards, so God is saying here that a person who controls his temper is better than that.)
“Do not make friends with a hot-tempered man, do not associate with one easily angered, or you may learn his ways and get yourself ensnared.” (Proverbs 22:24,25, NIV)
“He who guards his lips guards his life, but he who speaks rashly will come to ruin.” (Proverbs 13:3, NIV)
“The tongue that brings healing is a tree of life, but a deceitful tongue crushes the spirit.” (Proverbs 15;4, NIV)
*NIV means New International Version
Note: The Book of Proverbs (Old Testament) and the Book of James (New Testament), of all the books of the Bible, are especially noted for having much to say about our talk.

When people ask my pastor friend if he’s in Facebook he says, “No, but I have my face in The Book.
