What is Heaven? / Where is Heaven?

The ABC program 20/20 ran a show on Friday July 6, 2012 on the topic of heaven. Barbara Walters was the host and it ran for 2 hours, and the 2 questions "What is Heaven?, and Where is Heaven? was given to a series of religious leaders and hollywood entertainers. The responses were were interesting within themselves, since all of had their own view. 

The following is a Biblical view of these 2 questions, there are 739 times the word "heaven" is used in the Bible in 691verses.  From Genesis to Revelations this topic of heaven is discussed and describe. 

I will like to just reference one passage of Scripture that describes how to get there, and who is there. John 14:1-11 Jesus is speaking

^14:1 “Do not let your hearts be distressed. You believe in God; believe also in me. ^14:2 There are many dwelling places in my Father’s house. Otherwise, I would have told you, because I am going away to make ready a place for you. ^14:3 And if I go and make ready a place for you, I will come again and take you to be with me, so that where I am you may be too. ^14:4 And you know the way where I am going.” ^14:5 Thomas said, “Lord, we don’t know where you are going. How can we know the way?” ^14:6 Jesus replied, “I am the way, and the truth, and the life. No one comes to the Father except through me. ^14:7 If you have known me, you will know my Father too. And from now on you do know him and have seen him.”

^14:8 Philip said, “Lord, show us the Father, and we will be content.” ^14:9 Jesus replied, “Have I been with you for so long, and you have not known me, Philip? The person who has seen me has seen the Father! How can you say, ‘Show us the Father’? ^14:10 Do you not believe that I am in the Father, and the Father is in me? The words that I say to you, I do not speak on my own initiative, but the Father residing in me performs his miraculous deeds. ^14:11 Believe me that I am in the Father, and the Father is in me, but if you do not believe me, believe because of the miraculous deeds themselves.
