Lying is a sin. It says that we shouldn't do it right in the Ten Commandments. So why do we do it?
"Do not steal. Be honest in what you do. Do not lie to one another." ~ Leviticus 19:11
"Do not lie to each other. You have put out of your life your old ways." ~ Colossians 3:9
You have put away your old life and brought in the new. You don't have to nor should you want to lie anymore.
Yes, this is a very short chapter, because I couldn't find a whole bunch of verses telling you that lying is wrong, but I just wanted to make sure you guys knew it was wrong to lie.
