Apart from the fact that Mary was still alive for much of the time reported by the New Testament,
why do you think that the dead cannot pray for us? Are the dead indifferent to us? Does your mother cease to be your mother after she has passed away? In AC, the martyrs whom John describes in his Revelation are definitely aware of what is occuring on earth.
Yeah the dead are different from us......THEY ARE DEAD!
I believe the dead can not pray for us because the Bible doesn’t say that they can.
Revelations talks about the prayers of the saints. Saints in the New Testament refers to living believers. Revelations uses symbolic language when it talks about the prayers being as insense.
Your assumption that those ‘prayers of the saints’ are prayers of dead believers used as intercession is because of your other preconcieved ideas, not because the Bible supports it.
In heaven, my mother, father, and wife will be different then what I think of them now on Earth. (Matthew 22:30)
