Enoch and Elijah were “removed.”. Many are of the opinion that they will be the two winesses of Revelation.
Could be.
We don’t know where Enoch and Elijah are; just that God took them but if we follow the early rapture mantra, God removes the CHURCH (believers) and of course we know, Enoch and Elijah were not the only believers.
Elijah was carried away, via a whirlwind, to another place. He was taken there presumably so his presence wouldn't impede or otherwise diminish his successor Elisha.
He was taken up by the whirlwind under the reign of Jehoshaphat. But he sent a letter, thirteen years later, to the Jehoram, the son of Jehsoshaphat and it's chronicled in Chronicles:
2Ch 21:12 And a letter came to him from Elijah the prophet, saying, Thus says the LORD God of your father David: Because you have not walked in the ways of Jehoshaphat your father, or in the ways of Asa king of Judah,
This passage usually gives those who think that Elijah went to heaven fits because it doesnt' fit into their narrative so it's usually tried explain away. But NOBODY has gone to THE heaven. Jesus Christ made that clear:
Joh 3:13 No one has ascended to heaven but He who came down from heaven, that is, the Son of Man who is in heaven.
No one has ascended, gone up to, heaven. Jesus said it himself.
