Let me start by Saying Yes. Only The Truth Can Set you Free. Now when i say "Set Free" i am not talking of you gain freedom from the people of this word (Cell), but gaining freedom from your Mind, When you tell lies, a voice in your mind Speak to you that you have committed a sin and you may live with that still the rest of your life. But when you tell the Truth, you have nothing to hide and ur mind will be at rest all the time.
