It is not who anyone says that you are that matters. It is who God says that you are that really matters. And only you can make that determination. Your connection to God is never blocked by anything you or anyone else does. He continues to speak to you, even in your worst behavior, just as He did with Lucifer, and later, Cain after murdering his own brother Abel.
Try as you may, you can never be free from God and His control over your life. He is a father to you, more than your own father is a father to you!
