Only a Child Is Innocent: What is Heaven?

I once spent time with a couple who had just lost their only, very young child, their daughter.  Like many other people who have lost loved ones, they asked about Heaven.  We take a survey of Heaven, looking at the current Evangelical interpretation, and then stepping back and walking through time, from the 100's A.D. to the Middle Ages, to the Renaissance, and to the emergence of the "Social Gospel".  Our goal is to see what Scripture tells us about the nature of Heaven, and to consider the highly varied interpretations of Heaven that have emerged from the minds of Christian Theologians.  Then we ask the question: What does it all mean?
