There is a path of life, a path to Paradise, and like every journey, there is a door, and a path to follow.  Moses started writing about that path of life to Paradise, and the Door to enter that path - after he encountered Who was causing the bush to burn yet not be consumed.  Moses was set upon his personal journey toward Paradise as he surrendered to and followed Whose glory was filling the bush with supernatural fire and supernatural light and life from Himself.  

This was the journey from Eden lost - to Eden Regained  in all it's golden endless glory. 

Issa, Jesus Christ, Yeshua  told of this path of life and it's door of entrance and Who gave the burning bush it's flaming glory but not being damaged by the fire.  

Starting with the path of life and it's door as Issa / Jesus / Yeshua told it, in His parting words in the Engeel ( Bible ) . He tells the Apostle Peter that once seeking to enter this path through Heaven's Door this happens inside the surrendered follower. 1 Peter 1:23  Being born again, not of corruptible seed, but of incorruptible, by the word of God, which liveth and abideth for ever.

Matthew 28:
18  And Jesus came and spake unto them, saying, All power is given unto me in heaven and in earth.
19  Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost:

20  Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the world. Amen.

By looking constantly to Jesus, from morn till eve, with the eye of faith, we shall be strengthened. God will make the most precious revelations to His hungering, thirsting people. They will find that Christ is a personal Savior. They feed upon His word, for it is spirit and life. This word kills the natural, earthly nature, and a new life in Christ Jesus is created. The Holy Spirit comes as a Comforter to them. Love takes the place of hatred, and the heart receives the mold of the divine similitude. The image of Christ is reproduced in the human agent, and by the transforming efficacy of the grace of Christ he becomes a new creature. "As many as received Him, to them gave He power to become the sons of God, even to them that believe on His name: which were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God" (John 1:12, 13). This is the new birth.  {10MR 166.1}
