This song is based on verses from the book of James chapters 1 and 3. I think it speaks for itself, but this is directed toward other Christians. You really should just go read James.

Lyrics:

Let us be swift to hear and slow to speak

Slow to wrath, for we work not righteously in wrath

Doers of the word, not hearers only, deceiving ourselves

So the tongue's a little member, behold such a flame

And the tongue is a fire, no man can tame
