The Evil Tongue Is The Lying Tongue

Lie not to one another: Col 3:9  Lie not one to another, seeing that ye have put off the old man with his deeds; 

The Cretians were noted for liars: Tit 1:12  One of themselves, even a prophet of their own, said, The Cretians are alway liars, evil beasts, slow bellies.

It becomes not Christians to be Cretians.

Nothing is more contrary to GOD than a lie; it shows much irreligion; lying is a sin that does not go alone, it ushers in other sins.

Absalom told his father a lie, that he was going to pay his vow at Hebron: 2Sa 15:7 and this lie was a preface to his treason.

Lying is such a sin, as takes away all society and converse with men; how can you have converse with him, that you cannot trust a word he says?

It is a sin so sordid, that when the liar is convicted, he is ashamed.

God's children have this character, they are children that will not lie" (Isaiah 63:8), the new nature in them will not suffer them. 

The liar is near akin to the devil, and the devil will shortly claim kindred with him, "The devil is a liar, and the father of it" (John 8:44).

He seduced our first parents by a lie (Genesis 3:4).

How does this sin incense God?

He struck Ananias dead for telling a lie (Acts 5:5). 

The furnace of hell is heated to throw liars into,  For without are dogs, and sorcerers, and whoremongers, and murderers, and idolaters, and whosoever loveth and maketh a lie. Rev. 22:15
