Man has a conscience, that small voice that tells you if what your are doing is right or wrong. If we behave wrongly, it becomes an accusing voice that reminds us continuously. It is important to hear our conscience's voice and not quiet it, because when forced silent or ignored, it loses its sensitivity and hardens, this is very dangerous, because the conscience is an alarm system for our good that lets us judge ourselves and through it God invites man to repent.
