Has anyone ever ascended into heaven?

No one has ascended into heaven.

No man hath ascended up to heaven, but he that came down from heaven, even the Son of man which is in heaven. John 3:13

Some have ascended into heaven.

Enoch did.

And Enoch walked with God: and he was not; For God took him. Genesis 5:24

Enoch was translated that he should not see death; and was not found, because God had translated him. Hebrews 11:5

And so did Elijah.

And Elijah went up by a whirlwind into heaven. 2 Kings 2:11
