John 14:2-3

In My Father’s house are many dwelling places. If it were not so, I would have told you, because I am going there to prepare a place for you. And if I go and prepare a place for you, I will come back again I will take you to Myself, so that where I am you may also be.  

Jesus is coming back for His people. We may not be able to see heaven from here, but the Bible assures us it exists. Jesus is preparing a place for believers just as He did for the disciples. Our promise from God is eternity for those who are saved.
