To Tell or not to tell

When is it right to NOT tell someone that they are really ill? Are you trying to protect them or are you trying to control them? Is it really ok not to tell someone that they have cancer? Then the next question should be WHEN do you tell them?
  I believe that the person who has Cancer should be told as soon as possible so they wil have a fighting chance. I wonder sometimes if people are scared of what might happen. Do they think that their loved one will not want to live? Do they think that their loved one might kill themself? I believe that all of those thougths cross peoples minds and more than once or twice.
   How can God get the glory of HEALING someone with cancer if they are not diagnoised and treatment started? ONLY God can heal. he heals through Doctors and Surgeons, but it is really God who heals.
  Let the Lord heal your soul. Sin is like cancer. It will eat away your soul if you do not cut it out of your life. The only way to cut it out of your life is to ask Jesus Christ to forgive you of your sin and to cleanse you as white as snow.
  It is truely something where you can take something RED to change the color of something BLACK to WHITE. That is what happens when Jesus cleans you. It is by His Blood that you are made whole. Don't let the sin eat away your soul. Go to the Great Physician Jesus Christ.... your appointment is now...the Holy Ghost is calling your name, waiting for you to answer "Here am I"
