You know the way people say of someone, 'they are so heavenly minded that they are no earthly good.'  I think that is nonsense.  If we really understand what heaven is like then we will be motivated to productive Christian living.  I would like to suggest that most of us are actually in danger of being no earthly good because we are not heavenly minded enough.  Anyway, in the following clip Randy Alcorn will talk about heaven and how it affects our life now.

Before you look at that clip I want to mention something about what happens after the Christian dies.  It is my understanding that when we die we will go straight to be be with the Lord.  The apostle Paul talks of departing (death) and being with Christ (Philippians 1:23).  Similarly Jesus told the repentant thief on the cross that 'today you will be with me in Paradise'.  However, though we are with the Lord after death we will still await the time when he returns to earth, so that we can receive our glorious resurrection bodies (see 1 Corinthians 15).
