Belief in God/video games/hearing satan’s voice

Recently, our 7.5 year old son said something pretty startling.. out of the blue he says he doesn’t feel he believes in God. We homeschool and are very committed Christians. He cried so much as he told us this and he said he felt guilty for this. He says he thinks he doesn’t believe God because he learnt that we can’t just say we believe God and not obey God and the Bible. He thinks he doesn’t obey God because he doesn’t really want to pray or read the Bible and he strongly desires to play video games even when we’ve told him to drop the subject. He has been asking us to get him a switch to play super Mario brothers with his dad. We gave him a strong ‘no answer’ till maybe he’s 18. He would cry uncontrollably about this because he thinks that his dad might die by the time he’s 18 because we’re older parents. What’s worrying is that he said he has been hearing satan tell him that if he doesn’t step on the lines in the pavements or floor for 3 months, then he will get the video game. He is a deep thinker at 7, but has very strong feelings, a strong will and a very imaginative mind. Thank you for your thoughts and suggestions.
