All I will say at this point is that John 3:13 is a greatly misunderstood and misapplied Scripture. But if you go to Hebrews 12:22-24, you will discover that all the saints who have passed on are now in Heaven, in the New Jerusalem. Of course Enoch and Elijah went to Heaven without physical death.
Hebrews 12:22-24 says nothing of anyone being in the third heaven where God, Christ and all His holy angels dwell. If you go back to vs. 5 and read through vs. 24 this is an exhortation to endure God's chastening. Those who are God's own from the beginning have their names written in heaven and we endure here on earth by seeking those things from above which is the Spiritual Jerusalem, Colossians 3:1-4.
Gen 2:7 And the LORD God formed man of the dust of the ground, and breathed into his nostrils the breath of life; and man became a living soul.
Gen 3:19 In the sweat of thy face shalt thou eat bread, till thou return unto the ground; for out of it wast thou taken: for dust thou art, and unto dust shalt thou return.
Ecc 12:7 Then shall the dust return to the earth as it was: and the spirit shall return unto God who gave it.
1Th 4:15 For this we say unto you by the word of the Lord, that we which are alive and remain unto the coming of the Lord shall not prevent them which are asleep.
1Th 4:16 For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first:
1Th 4:17 Then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord.
Rev 20:6 Blessed and holy is he that hath part in the first resurrection: on such the second death hath no power, but they shall be priests of God and of Christ, and shall reign with him a thousand years.
Rev 21:1 And I saw a new heaven and a new earth: for the first heaven and the first earth were passed away; and there was no more sea.
Rev 21:2 And I John saw the holy city, new Jerusalem, coming down from God out of heaven, prepared as a bride adorned for her husband.
Enoch and Elijah are not in the third heaven where God sits on His throne. Many have always taught that they are, but scripture says different.
Gen 5:24 And Enoch walked with God: and he was not; for God took him.
Hebrews 11:5 By faith Enoch was translated that he should not see death; and was not found, because God had translated him: for before his translation he had this testimony, that he pleased God.
Does not say Enoch was taken up to heaven, but that he was only translated that he should not see death at that particular time of his life and that he was not found. Should not see death means since Enoch walked with God he would not see the second death, Rev 20:6, but only that of the first death, Hebrews 9:27, as all his days were three hundred and sixty as he died, but no one knows where.
2Ki 2:11 And it came to pass, as they still went on, and talked, that, behold, there appeared a chariot of fire, and horses of fire, and parted them both asunder; and Elijah went up by a whirlwind into heaven. (Heaven here means atmosphere, first heaven)
Elijah, having ascended into the air by a whirlwind was carried away out of sight beyond the horizon. Several years after he was taken away King Jehoram received a letter from him. How long after? There are some difficulties in figuring the exact chronology as it varies from 2 to 10 years or more. A note in Josephus (a Jewish historian of the first century A.D.) says 4 years, while the JEWISH ENCYCLOPEDIA figures it at 7 years.
Regardless of the exact number of years there came writing to Jehoram from Elijah the prophet, saying..." (2Chron 21:12). Now the wickedness of Jehoram, for which he was being rebuked in the letter, took place after Elijah was taken away, yet the letter speaks of these things as past events, and the punishment to come upon him as yet future. So the idea of some, that Elijah wrote the letter before he was removed by the whirlwind, is proved wrong.
Elijah was taken up by the whirlwind into the first heaven and transported to another location on Earth.
