Don't be so sure on the asleep dogma...

Matthew 27:52-3
52And the graves were opened; and many bodies of the saints which slept arose, 53And came out of the graves after his resurrection, and went into the holy city, and appeared unto many.

Jesus preached to "the captives" and when he rose so did they. They were not asleep for to be absent from the body is to be present with the Lord.

2nd Corinthians 5: 6-8
Therefore we are always confident, knowing that, whilst we are at home in the body, we are absent from the Lord: 7(For we walk by faith, not by sight:) 8 We are confident, I say, and willing rather to be absent from the body, and to be present with the Lord.

But it's NOT Mary that will be coming but Yeshua!
