I know someone who complains a lot, often about someone else complaining. You give him some good, sound advice and he responds as if he avoids responding to you directly as if he hasn't heard you at all. This has happened numerous times. I can only conclude that we can tell someone all about how good God is and if that person does not open up, you can not make him believe. That person is the only one who can let God into his heart and his life. We each hold the key to open the door to let God in.
