How do you tell a person to stop tell liars?

Pray to god go to church and ask for forgivenees

Answer:

Just stop. If you lie, not knowing you are lying then you should seek professional help.

A useful trick is to make a deal with yourself that you will destroy something you like (a 10 dollar bill, a treasured photo) each time you lie. Then do it. If you can't, then you don't want to stop. If you follow through then you will find it easy to stop after a few penalties.
