What does the Bible say about Slander?

Thank you Warqar Daniel, for posting this. This is a great lesson and should be studied. We are servants of CHRIST, and as HIS servants we should act according to our MASTER'S WILL. Acting in a way that is considered slanderous, is not acting as a CHRISTIAN shoud act. We should gaurd our heart, and fill it with the LOVE of JESUS, and not habour hatred or evil as what is found in our hearts, becomes evident within our speach.

Where does slander come from? The scripture you have given is very appropriate:

Luke 6:45 A good man out of the good treasure of his heart bringeth forth that which is good; and an evil man out of the evil treasure of his heart bringeth forth that which is evil: for of the abundance of the heart his mouth speaketh.

So, slander comes from an evil heart. Futhermore, what is abundant in our heart, os also made know from our own mouths.
