Prayer comes in many forms. Of course it is the route to the heart of God and to the pentacle of God's strength and power in us.  It is the interlude of embrace through which we become more acquainted with His Spirit.  Prayer is the vehicle upon which change is delivered to the heart of man.  From the Throne room of God is from where acceptance and atonement is received through prayer.
As the Prophet Elijah traveled through the desert wilderness of Israel, though he had no scroll, he had communication with God Himself.  Prayer is that communication with God. This communicational relationship was such that Elijah did not see death, but was carried to heaven in a whirlwind. 

Elijah established a loving, passionate relationship with the Lord.  So much that the Lord was present to talk back with him through all of this trials and perplexities.    As the scripture says, "kiss the son"  Elijah did this with not only prayer, but his life, and the Lord became his close guide and friend, as a compassionate father.

Enoch walked with God through much relationship and was shown the return of Jesus Christ with His saints. He also experience his own rapture.  The Bible says hew was not, because God took him.  He did not see death, but was allowed Heaven's gates without suffering the pains of death.

Jude:1:14: And Enoch also, the seventh from Adam, prophesied of these, saying, Behold, the Lord cometh with ten thousands of his saints,

King David spoke of these pains of death that the Lord allowed the men to miss.

Ps:55:4: My heart is sore pained within me: and the terrors of death are fallen upon me.
