God has told us not to judge each other as well, lest ye be judged yourself.
How do you know God does not hear their prayers or will not answer them? You are wrong and bordering on blasphemy.
Christ himself associated with sinners, thieves, prostitutes and treated them with love and tried to show them the way. He did not tell them his father would not answer or hear their prayers. You should be ashamed of yourself! I do hope you'll be praying for forgiveness this evening.
