After my devotional at choir on Wednesday, Lee recommended the book “Heaven” by Randy Alcorn. I had the opportunity to hear Randy speak at the "Worship God 06" conference I attended a few days ago. I have also heard him speak at John Piper's pastors conference. In the most recent talk, he shared some amazing insights from the book about what heaven will be like. All his work is based upon years of Biblical research.
I own his book “Heaven” but have not yet had the opportunity to read it. In light of Lee's recommendation on Wednesday and based on the reviews I have heard, and the content of Randy’s talk, I am sure the book is a must read. You can link to more information about his book here.
