Do My Prayers Really Reach Heaven?

When the disciples came to Jesus and asked Him to teach them to pray, He said, "This is how you should pray:  ‘Our Father in heaven...’" Stop!  But just where is heaven?  Literally the words are "in the heavens."  The space that surrounds planet earth is really pretty vast, right?  Is this what He is talking about?  Yet, if you are in China and look overhead, you're looking at the opposite direction of our friends in Quito, Ecuador who are listening to this program.  Just where is the dwelling place of the Father? For a few moments, think with me about how vast the heavens really are.
