As the author suggested, when planning a trip to an unknown place, it is wise to prepare ahead. Study that place. Think on it so that upon arrival, you'll feel comfortable. As a Christian, I plan on going to Heaven, and I appreciate the efforts the author employed to compile this tome.
In addition to many verses from the Bible, Alcorn used his extensive collection of material for his opinions. Although it is an intimidating work with 535 pages, I must say, it's worth the read. (I read a chapter or two each day until finished. It might serve well for a group study.)
The one caveat I have is the repetition. It should have been edited more carefully.
I like how the writer quotes verses from the bible and at the same time gives his opinion trying not to form his own theory or ideas. The writer has done a good research about heaven and I liked it because you usually don't get this information from a pulpil at church. It helps to continue with your faith knowing that God has something special for us in eternity. And I like the expectation of seeing him face to face.
Using the book in a Bible Study group and it is very well received by all the member. He is detailed in the description of Heaven and backs it up with verses from the Bible. Makes believers look forward to our next life and makes you want to tell others of what they will be missing if they do not embrace the Gospel of Jesus.
