And it came to pass, when the LORD would take up Elijah into heaven by a whirlwind, that Elijah went with Elisha from Gilgal... 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. (2 Kings 2:1,11)
In spite of these two clear statements, there are some who refuse to believe that Elijah went to Heaven. There are others who refuse to believe that Enoch went to Heaven. And then there are others who refuse to believe that all the OT saints along with the NT saints who have passed on are now in Heaven, in the presence of God and Christ.
