@ReganB, I am sorry to hear about your friend with Asperger’s experiencing a difficult time right now. Praise God for your willingness to reach out to him. Many a times Aspergers co-exists with anxiety disorders adding to the complexity of social problems. It is very possible that he has been misunderstood or experienced rejection due to difficulty in understanding social perspectives and lack in planning/organizational thinking. Considering the social and psychological difficulties of those with Aspergers, I really hope the community around him comes together to build the bridge needed as long as he is safe to be with.
I have had some exposure to understanding this condition among family and friends. Here’s a chart that shows how Aspergers can affect spiritual life I found online on Key ministry -
Getting professional counsel to ensure safety comes first which is beyond the scope of this forum. I can share what I have seen as helpful and direct you to some resources. In my experience, showing acceptance for who they are and their unique perspectives is so needed. If he has a high regard for the Bible, I would start affirming truth from scripture for every lie he utters. Satan is the father of lies and when someone is not thinking clearly, he loves to whisper lies , whether they are on the spectrum or not. Many families prefer smaller groups rather than regular church services to meet the spiritual needs of those on the autism spectrum. I think housechurch may be a great option long term.
For some practical guidance, here are some resources I have come across.
May the peace, wisdom and love of Jesus direct you as you seek to help your friend. God bless!
