Crossing the Bridge to heaven

In Christianity, Heaven is the promised reward of Christ for those who follow His steps on this earth. 
This promise begs the question: Where is heaven? How is it? How do we arrive at this promised land?
For starters, we need spiritual introspection to follow the path that leads to heaven, because at the end of our lives our choices will lead us ultimately to one of two utterly different destinies, heaven or hell, with crucially different consequences. And this is so because even though heaven and earth are connected, heaven also has an opposite.
We already have a good glimpse of hell by living in this valley of tears ruled by Satan where the gravity of this earth anchors us to this world.
The author offers a brief reflection that aims to answer these questions for those who might be interested in heaven as a final destination that Jesus Christ has prepared for us to enjoy with Him the presence of God.
