Ephesians 4:29 KJV — Let no corrupt communication proceed out of your mouth, but that which is good to the use of edifying, that it may minister grace unto the hearers.
Speak the truth. But cussing folks out and showing hate is not it! Sis is in error. Repent!
Colossians 3:8 KJV — But now ye also put off all these; anger, wrath, malice, blasphemy, filthy communication out of your mouth.
