She's dead according to Scripture, when it says all... all must die.
You have been referenced the same Scripture (Hebrews 9) twice and choose to ignore it! Was Mary a person?
So, I repeat myself...
Hebrews 9: 27 Just as people are destined to die once, and after that to face judgment, 28 so Christ was sacrificed once to take away the sins of many; and he will appear a second time, not to bear sin, but to bring salvation to those who are waiting for him.
Do you not believe that the saints in heaven, including Mary, will greet the chosen at the 2nd coming of Our Lord Jesus?
