I am just finishing a book entitled Heaven by Randy Alcorn. He takes generally held beliefs and common questions and addresses them structurally. He does instill some of his own thoughts on some of the topics, but he is quite clear when they are merely his thoughts and not necessarily scriptural. He speaks of the new heaven and the new earth, and our relationship with God. It was given to me by my pastor on the occasion of my father being called to his heavenly home, and has brought some comfort to what I already viewed as a blessed occasion.
