When you're laughing at that quip and everyone around you seems to be having a good cachinnation... look around to find at who's expense this laughter seems to come... the one who's smile is forced, who stands trying to dismiss or disregard the words said in jest that still cut too close. For while this person may be 'a good sport' and to only come back with their own crack... when no one's looking they may absorb those words more than anyone could guess...

Just been a challange to me lately... anyway...

James 1:26  If any think they are religious, and do not bridle their tongues but deceive their hearts, their religion is worthless.

1Peter 3:10  10  For, "Whoever would love life and see good days must keep his tongue from evil and his lips from deceitful speech.

Ephesians 5:4  Entirely out of place[among christians] is obscene, silly, and vulgar talk; but instead, let there be thanksgiving.
