Deut 4:1
4:1 Now listen, Israel, listen carefully to the rules and regulations that I am teaching you to follow so that you may live and enter and take possession of the land that GOD, the God-of-Your-Fathers, is giving to you.

Another way to word this for us regarding Heaven is: Now listen, listen carefully to the rules and regulations that I am teaching you to follow so that you may live and enter and take possession of the land that GOD is giving to you, Heaven.
