Heaven by Randy Alcorn
I enjoyed this book and refer to it frequently. It has an immense amount of information about the subject, Heaven, and is well supported by biblical references. As important as this subject should be to Christians, seldom is it mentioned other than in passing. Yet it should be our great hope and encouragement. This book is written in layman's language and captures the reader's attention. It is difficult to put down. It is also a great reference work.
