I must politely disagree:
(James 1:26) “Those who consider themselves religious and yet do not keep a tight rein on their tongues deceive themselves, and their religion is worthless.”
(James 3:10) “Out of the same mouth come praise and cursing. My brothers and sisters, this should not be.”
(Matthew 5:11) “It is not what goes into the mouth that defiles a person, but what comes out of the mouth; this defiles a person.”
(Matthew 12:36) “I tell you, on the day of judgment people will give account for every careless word they speak,”
(Colossians 3:8) “But now you must put them all away: anger, wrath, malice, slander, and obscene talk from your mouth.”
