And 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 KJV
Wasn't Jesus born from Mary and did not come down from heaven?
Also wasn't he on earth and not in heaven when he was born?
No man has ascended because no man was good enought before Christ , people were not going to heaven but to sheol - the place of dead both forgiven and not .
That's why Christ had to go to sheol after he died on cross to preach to these souls here what he has done . Also there is difference between Ascending and Being Raptured/Taken Away . Only Christ on it's own could ascend , other people were taken by God because they had no power to do so by themselfes .
Yes Jesus was not born of Mary but had his flesh born of Mary there is difference . He is eternal God as we see in Isaiah 9:6
For unto us a child is born, unto us a son is given: and the government shall be upon his shoulder: and his name shall be called Wonderful, Counsellor, The mighty God, The everlasting Father, The Prince of Peace.
child is born = Christ's body
son given = Christ incarnate into body , he is given by God because he existed before that
his name.. The mighty God , The Everlasting Father - Christ is both the Son and The Father, he was both in heaven and on earth in fleshly body .
Jesus even himself said that about himself while being on earth in John 3:13 because Son Father and Holy Spirit are one .
The only place where Christ was separated from God was on cross because he was dying in your place for your sins .
