Before reading comments on your post I know what I am going to find. Just a trick of the mind, just the oxygen leaving the brain causes such events.
I bet you will get some rather disturbing remarks from your post.
People have strayed so for away from God they hold no belief in life after death.
While I have never experienced this near death event in my life I do carry a peace as you describe. It is a peace I have everyday because I love the Lord Jesus Christ and only he gives such peace.
no belief in life after death - if there is no cause for belief in life after death, then everything - everything - is meaningless and there is no right nor wrong, IMHO (and in JCHO)
Actually, most of the comments directed to me personally were very positive. I haven't gone back to look at the thread. It's 9AM where I live, way past my bedtime. I'll look 'tomorrow'. I believe as you do and carry with me a similar peace that I try to share with others.
