I was thinking about the questions raised during the Chicken and Egg conference...

Why didn't God give us all the details of Heaven? Why didn't the Bible tell us about His plans for the angels?

Let us consider this analogy:

If you were to write a civics textbook, instructing people on how to lead their lives, would you include chemistry, physics, biology, or even maths in this textbook of yours? Would you tell the people abt protons, electrons and all the teeny-weeny things that constitute this universe?

God's purpose is not to give us facts on this (perishable) world. God's purpose is to teach us how to be good christians. Frankly, anything other than that is unimportant.
