Is there a human being in heaven ? let's look at the book of Hebrew 11 Vs 13
These all died in faith not having received the promises, but having seen them afar off , and were persuaded of them, and embraced them, and confessed that they were strangers and pilgrims on the earth "
No man has ascended apart from our Lord Jesus Christ, in order to clear doubt let's look at book of John 3:13.
And no man hath ascended up to heaven, but he that came down from heaven, even the son of man which is in heaven
Jesus made it clear that no man has ascended to heaven, according to the Bible, there is only one person who was recorded to have ascended to heaven and that person is he who descend from heaven, in the book of John 6 vs 38, Jesus Christ said that he descend from heaven not on his own will buy the will of who sent him. Ephesians 4 Vs 10 says
He that descend is the same also that ascended up far above all heavens, that he might fill all things
Apostle Paul described that Jesus was the only one who ascended to Heaven.
